Technical Info
| Digital microscope is the general term for microscope that can convert an optical image into a digital image, and usually does not specifically refer to a certain type of microscope. It should be noted however that most microscopes can be mounted with cameras and display devices to change to digital microscope. Microscopes in the visible range, from the digital imaging point of view, all use CCD or CMOS sensors to image the optical signal as an electric signal on a computer or display. However, the difference between various kinds of digital microscopes mainly comes from the optical microscope itself, so it is necessary to look at the imaging effect and function of the optical part in order to select the type of digital microscope. From the classification point of view, digital microscopes can be divided into: digital biological microscopes, digital stereo microscopes, etc. It should be noted that due to the variety of lenses, ordinary lenses or microscopes, if mounted with a digital camera, can all become a digital microscope. At present, the trend of digital microscopes is not only to present simple digital images, but to collect, process and analyze images through back-end software, especially for image measurement, comparison, judgment, and large-format scanning and splicing, and three-dimensional synthesis and so on, these aspects have been widely developed and applied. |
| Microscopes and components have two types of optical path design structures. One type is finite optical structural design, in which light passing through the objective lens is directed at the intermediate image plane (located in the front focal plane of the eyepiece) and converges at that point. The finite structure is an integrated design, with a compact structure, and it is a kind of economical microscope. Another type is infinite optical structural design, in which the light between the tube lens after passing the objective lens becomes "parallel light". Within this distance, various kinds of optical components necessary such as beam splitters or optical filters call be added, and at the same time, this kind of design has better imaging results. As the design is modular, it is also called modular microscope. The modular structure facilitates the addition of different imaging and lighting accessories in the middle of the system as required. The main components of infinite and finite, especially objective lens, are usually not interchangeable for use, and even if they can be imaged, the image quality will also have some defects. The separative two-objective lens structure of the dual-light path of stereo microscope (SZ/FS microscope) is also known as Greenough. Parallel optical microscope uses a parallel structure (PZ microscope), which is different from the separative two-object lens structure, and because its objective lens is one and the same, it is therefore also known as the CMO common main objective. |
| The magnification of the objective lens refers to the lateral magnification, it is the ratio of the image to the real size after the original image is magnified by the instrument. This multiple refers to the length or width of the magnified object. System optical magnification is the product of the eyepiece and the objective lens (objective lens zoom set) of the optical imaging part within the system. Optical magnification = eyepiece multiple X objective lens/objective lens set The maximum optical magnification of the microscope depends on the wavelength of the light to which the object is illuminated. The size of the object that can be observed must be greater than the wavelength of the light. Otherwise, the light cannot be reflected or transmitted, or recognized by the human eye. The shortest wavelength of ultraviolet light is 0.2 microns, so the resolution of the optical microscope in the visible range does not exceed 0.2 microns, or 200 nanometers. This size is converted to the magnification of the microscope, and it is the optical magnification of 2000X. Usually, the compound microscope can achieve 100X objective lens, the eyepiece is 20X, and the magnification can reach 2000X. If it is bigger, it will be called "invalid magnification", that is, the image is large, but the resolution is no longer increased, and no more details and information can be seen. |
| The brightness of the light source adjustable is very important in the imaging of the microscope. Since the difference of the numerical aperture of the objective lens of high magnification and low magnification is very big, more incident light is needed to achieve a much better resolution when using a high magnification objective lens. Therefore, when observing through a high magnification objective lens, the brightness required is high; when observing through a low magnification objective lens, the brightness required is low. When observing different objects, or feature points of the same object at different positions, the brightness needs are also different; including the difference of background light or reflection within the field of view of observation, it has a great influence on the effect of observing the object, and therefore one needs to adjust the brightness of the light source according to each object to be observed. In the light source capable of providing continuous spectrum, such as a halogen lamp, the brightness adjustment of the light not only adjusts the brightness and intensity of the light, but also changes the spectrum emitted by the light source. When the light source is dark, there are many components of red light, and when the brightness is high, there are more blue spectrum. If the required light is strong and the spectrum needs to be changed, the light can be kept at a brighter intensity, which is solved by adjusting the spectrum by adding a color filter. Take note of the dimming button on the light source, after the On/Off switch is turned on, normally clockwise is to brighten, and counterclockwise is to darken. If it is adjusted to the lowest brightness, the light source should normally be lit. If the naked eye still can't see the object being illuminated brightly, you need to adjust the brightness knob to a much bigger position. Generally, there is scale marking on the dimming knob, which is an imaginary number representing the percentage of brightness, or an electronic digital display, giving the brightness of the light source under the same conditions a marking. |
| CMOS, or complementary metal oxide semiconductor. Both CMOS and CCD sensors have their own respective advantages and disadvantages. As a kind of photoelectric conversion sensor, among the current cameras, CMOS is relatively more widely used. |
 |
| The pixel is determined by the number of photosensitive elements on the photoelectric sensor of the camera, and one photosensitive element corresponds to one pixel. Therefore, the more photosensitive elements, the larger the number of pixels; the better the imaging quality of the camera, and the higher the corresponding cost. The pixel unit is one, for example, 1.3 million pixels means 1.3 million pixels points, expressed as 1.3MP (Megapixels). |
| Resolution of the camera refers to the number of pixels accommodated within unit area of the image sensor of the camera. Image resolution is not represented by area, but by the number of pixels accommodated within the unit length of the rectangular side. The unit of length is generally represented by inch. |
 |
| Digital signals output: USB 2.0, USB3.0; 15 Pin VGA; Firewire Port; HDMI; VGA; Camera Link etc. Analog signal output: BNC; RCA; Y-C etc. In addition, some cameras store and output images in the form of a memory card. Usually, industrial cameras often have several output modes on one camera for convenience purposes. |
| Boom stand is also called universal stand. It is a relatively large pole type stand. The height and length of the stand are big, and it can be freely adjusted in height, length and various angles. Its large weight ensures stable support and occupation of large space, but it can make the microscope free to move in a wide range with convenience. Boom stand is suitable for observing large objects. The direction of boom stand is flexible, and when in use, various kinds of positions and methods can be adopted, such as front, side, and tilt etc., to facilitate the layout of the workbench. On the side of the crossbar of the boom stand, a 5/8-inch connecting hole is generally left for connecting various focusing mechanisms and microscopes. The base of the boom stand usually only plays a fixing and supporting role. Under the observation of the microscope, it is an empty workbench, which can be used to place various platforms, work operating surfaces, and tools, etc., and can be freely combined into different working positions. When the base is large, the object to be observed can also be placed. In industrial places, most of the working positions are fixed. Sometimes, in one working position, a lot of tools, equipment and instruments need to be placed.. Because the microscope is relatively large in size and takes up also a relatively bigger space, and not convenient to move back and forth, therefore for purpose of use, the boom stand can be placed in an appropriate position, and does not need to occupy the most commonly used work tables. When in use, the microscope can be moved over, and pushed to the side when not in use. This is very suitable for use in electronics factories, installation and maintenance, medical and animal anatomy, archaeology and other industries. Boom stand generally does not have a fixed focusing device, and you can choose a variety of flexible accessories. Because the stand needs to ensure flexibility, therefore there are many locking buttons in all directions. In any time after adjustment, it must be ensured that each knob is in a locked state to avoid sliding, tilting and flipping of the microscope, thereby damaging the microscope and the items on the workbench. |
| The eyepiece of the microscope can have different viewing or observing directions. When the position of the microscope is uncomfortable, the direction of the eyepiece tube of the microscope can be adjusted, to facilitate observation and operation. Placement method of different viewing angles of the microscope: General direction: the support column is behind the object to be observed Reverse direction: the support column is in front of the object to be observed Lateral direction: the support column is on the side of the object to be observed Rotating eyepiece tube, different microscopes may have different methods, for some, the direction is confirmed when installing the eyepiece tube of the microscope, for some, by rotating the body of the microscope, and for some, by rotating the support member on the support or holder of the microscope. |
| Usually the universal joint is called E-Arm, i.e., Easy-Arm, also known as Universal Arm. Many people in the industry call it Bonder Arm, which refers to the components that connect the microscope on the COG Bonding Machine. At the tail of the E-arm there is a standard 5/8 inch (0.625 inch, 15.875mm) connector. The connector can be moved freely in both horizontal and vertical directions, and can also be fixed at an angular position in the vertical direction to facilitate microscope observation from different angles. E-arm can be connected to various kinds of microscope stands with 5/8-inch adapters, such as boom stand, flexible arm etc. It is also possible to connect various kinds of microscopes by adding or replacing different adapters. Note that, in general, these stands themselves are not directly configured with this E-arm, and separate purchase is necessary. |
| Camera mounting plate is a connection between the camera and the focusing mechanism. Camera usually comes with a standard whitworth thread (a British type of thread) adapter. Its specifications are: large diameter 1/4 inch, pitch 20 teeth / inch coarse teeth thread, expressed as UNC1/4-20. |
| Color filter is a type of filter that allows light of only a certain wavelength and color range to pass, while light of other wavelengths is intercepted. Color filter is made of colored glass, and it has various bandwidths and color for selection. Both artificial light source (lamp light) and natural light (daylight) are all full-color light, including seven colors, namely, red, orange, yellow, green, blue, indigo and purple. As the microscope illumination, different types of light sources have different color temperatures and brightness. In order to adjust the color of the light source, it is necessary to install a filtering device at the light exit port of the light source, so that the spectrum of a certain wavelength band is transmitted or blocked. Color filter generally can only be added to the illumination path to change the color of the illumination source and improve the contrast of the image, but generally it is not installed in the imaging path system, which affect the image quality. There are many types of color filters. In addition to the color requirements, color filters of different colors also contribute to the imaging quality. Color filters using the same color will brighten the color of the image. Of the traditional daylight filter, there are relatively more red and yellow light in the lamp light, the resolution is not high, and the observation is not comfortable. The use of daylight filter can absorb the color between yellow to red spectrum emitted by the light source, thus the color temperature becomes much closer to daylight, making microscope observation more comfortable, and it is one of the most used microscope color filters. Daylight blue filter can get close to the daylight spectrum, obtain more short-wave illumination, and improve the resolution of the objective lens. For example, using blue color filter (λ=0.44 microns) can improve the resolution by 25% than green color filter (λ=0.55 microns). Therefore, blue color filter can improve the resolution, and improve the image effect observed under the microscope. However, the human eye is sensitive to green light with a wavelength of about 0.55 microns. When using blue color filters for photomicrography, it is often not easy to focus on the projection screen. Yellow and green filters: both yellow and green filters can increase the contrast (i.e. contrast ratio) of details of the specimen. As far as the achromatic objective lens is concerned, the aberrations in the yellow and green bands are better corrected. Therefore, when yellow and green color filters are used, only yellow and green light passes, and the aberration will be reduced, thereby improving the imaging quality. For semi-apochromatic and apochromat objectives, the focus of visible light is concentrated. In principle, any color filter can be used, but if yellow and green filters are used, the color will make the human eye feel comfortable and soft. Red filter. Red has the longest wavelength and the lowest resolution in visible light. However, red light image can filter and eliminate the variegated background in the image. Therefore, so it has a very good effect for some applications that do not require color features for identification, and the edges and contours of the image are also the clearest, which is more accurate for measurement. Medium gray filters, also known as neural density filters, or ND for short, can uniformly reduce visible light. It is suitable for photomicrography and connection to computer monitors for observation. ND can be used for exposure control and good light absorption, and reduce the light intensity while not changing the color temperature of the microscope light source. |
| Fiber optic light source refers to an illuminating light source that does not contain or contains less spectrum of infrared heat radiation in a illuminating or light guiding body, for example, the popular LED light source, which is a typical illuminator fiber optic light source. In microscopic illumination, the optical fiber cold light source (commonly referred to as “cool light”) means that, after the illumination beam is transmitted through the optical fiber of the light guide body, the heat radiation is not brought to the light exit port, thereby achieving "cold light" effect. The portion of the illuminating light source of the optical fiber has been conventionally illuminated with a halogen light source. In recent years, high-power LED lighting has been widely used. Although the bulb of halogen light source can generate a lot of heat radiation, because of its high brightness when emitting light, it belongs to full-band light, with good color reproduction and comfortable observation by human eye, and therefore is still irreplaceable in some applications. Luminous light sources usually require a high-power light source to achieve strong light, therefore heat dissipation is very important. Whether it is a halogen light source or an LED light source, fan cooling is usually adopted. Fiber optic lighting application has many advantages: 1. The thermal conductivity of the optical fiber is poor. When the light source (light bulb) emits light, the thermal radiation, after being separated by the optical fiber, is not transmitted to the object to be observed. So, while maintaining the wavelength and brightness of the light, it becomes "cold light". When using strong light, cold light may not damage the observed objects, especially in medical and biological applications. 2. Single light source can be transmitted through the optical fiber, and at the same time there are multiple light-emitting points with the same light-emitting characteristics. The light-emitting port can be arranged at different positions and angles, or made into different shapes, such as double-branch lighting, ring lighting, multi-point lighting etc. 3. The light source host and the light exit port illumination point are transmitted through the optical fiber, and therefore the host can be placed in a safe or suitable position without affecting the illumination position of the light exit port, so that there will be more flexibility in design and use. 4. The light exiting port illumination point is transmitted through the optical fiber, and it can filter freely the wavelength of the light at the light source position in the front end of the light entrance, increase the polarization effect, and adjust the brightness and darkness. For example, improve the contrast and contrast ratio of the details of the object to be observed through various color filters, filter out the ultraviolet and infrared light, and reduce damage to certain items.. 5. In the light source host and optical fiber used in fiber optic lighting, the service life of the optical fiber can be decades, and the design separating the light source from the optical fiber makes the light source easy to repair and replace. |
| Optical fiber bundle for illumination, is referred to as optical fiber light guide for short. Optical fiber light guide is a fiber core made of transparent material (typically, glass fiber is made of silicon dioxide). Around the fiber core, a cladding layer is formed, using a material having a refractive index lower than that of the fiber core, that is, if the refractive index of the fiber core and the cladding layer are n1 and n2, then n1 must be >n2. The transmission of the optical fiber makes use of the principle of total reflection of light. In this fiber core medium, light is to maintain its characteristics of optical waveform for transmission, wherein the fiber core portion of high refractive index is the main channel for light transmission, while the outer casing of low refractive index covers the entire fiber core. Since the core has a higher refractive index than the outer casing, total reflection occurs, and therefore light can be transmitted in the fiber core. The core of the optical fiber is generally classified into glass fiber, quartz fiber, plastic fiber, and liquid core fiber etc. Microscope illumination usually uses glass fiber, which can have better transmittance for light of different wavelengths. For glass fiber, its optical core material is multi-component optical glass with high refractive index, whereas its cladding material is optical glass with low refractive index. The commonly used multi-component glass formula include: sodium-borosilicate glass (Na-B-Si), potassium-borosilicate glass (K-B-Si), sodium-zinc aluminoborosilicate glass (Na-Zn-Al-B-Si), and the like. Glass fiber, made of optical glass, has a much higher transparency than a ordinary set of glass, but still has a relatively high attenuation value, generally about 1dB/m. The lighting fiber optic wire is very thin, and cannot be bent at a large angle. Generally, its minimum bending radius ≥30D (Min. bending radius ≥30D). Check the breaking of the fiber optic wire, you can use one side section to face the light, and the other side section to see the dark part. If there is too much break, it can’t be repaired, but the entire fiber be replaced. |
| After unpacking, carefully inspect the various random accessories and parts in the package to avoid omissions. In order to save space and ensure safety of components, some components will be placed outside the inner packaging box, so be careful of their inspection. For special packaging, it is generally after opening the box, all packaging boxes, protective foam, plastic bags should be kept for a period of time. If there is a problem during the return period, you can return or exchange the original. After the return period (usually 10-30 days, according to the manufacturer’s Instruction of Terms of Service), these packaging boxes may be disposed of if there is no problem. |
