Scope Body PartsClose Λ
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.
Motorized Close Λ
The nosepiece of a microscope is generally switched manually. A motarized nosepiece is to add an electric motor onto the nosepiece to control switching of the nosepiece through the electric switch, so as to switch the objective used. This device can be added when some microscopes are bulky, switching of the objective needs to be kept steady, and needs to be frequently switched.
