Technical Info
| Nosepiece, also known as revolving nosepiece, can be mounted with several objective, and one of which in turn can be switched to the microscope optical axis for use. Nosepiece has different configurations, namely, single, triple, quadruple, and quintuple. Each objective has a ball buckle at its position to ensure that the objective is in the exact fixed position of the optical axis. Since any one set of objectives has the same parfocal distance, so when the objective is switched between high and low magnifications for observation, it is almost unnecessary to perform again the focusing operation. Nosepiece can be divided into two types, namely, inward nosepiece and outward nosepiece, depending on the positional direction. After switching, the tube of inward nosepiece is inclined to the side of the microscope body, which can save people's operating space and prevents it from hitting the lens. In general, after the objective is mounted onto the nosepiece, no special coaxial processing is required. If necessary, remove the nosepiece, and adjust the position of the end point screw on the dovetail rail behind the nosepiece. If the objective is still off-axis, adjust the optical axis of the condenser to match the optical axis center of the objective. In the use of microscope, if one set of objective cannot be parfocal, there are many reasons for the problem, but it may be that the nosepiece or the set of objective itself cannot guarantee parfocalness due to problems of processing precision. In this case, after confirming that the high and low magnifications of the objectives at both ends are in focus, adjust the objective of the middle magnification, and usually try to add a thin "shims" to correct. For normal switching of the objective, it is necessary to push the nosepiece instead of pushing and pulling the objective to prevent the objective and the nosepiece from deviating from the optical axis or loosening, so as to avoid image out of focus or damage. |
| Ring adapter is used for the nosepiece under the stereo microscope or the circular interface under the microscope objective, with appropriate threads to engage. The main function of the ring adapter is to connect the ring light. Some microscopes have grooves on their nosepiece, which can directly clamp the ring light, but it can easily damage the surface of the nosepiece of the appearance of the microscope, so it is more suitable to use an interface. Some ring adapters have one or two grooves on them, and they are used to clamp screw of the ring lights. There are also ring lights that are clamped on the Barlow lens of the microscope. If the lower end of the Barlow lens is threaded, an additional ring adapter can also be attached to clamp the ring light, so as to protect the surface of the objective. Usually, the ring adapter has very fine mounting threads. When the objective/ring adapter needs to be mounted, the mounting should be careful. Align the position of the nosepiece for installation to keep it completely “flat”. When it is blocked, remove it and install again, do not force it in. |
| When the object to be observed by the microscope has high temperature, corrosive solution or volatile gas, welding fumes, a ring adapter with glass can be used to protect the lens surface and isolate these factors that are destructive to the surface coating of the microscope objective. The glass of the ring adapter is generally optical glass, and it does not affect the imaging of the microscope, but because of the thickness of the glass, the working distance of some of the microscopes may be slightly increased. |
| 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. |
