Problems solved by technology

However, when a condenser is used for dark field observation, due to problems such as looseness and light leakage of the condenser, the circular beam is uniformly irradiated from the periphery of the optical system, not only cannot detect parts with microscopic defects and foreign objects, but also cannot detect the direction sexual defect

Abstract

The invention relates to a collecting mirror of a microscope, belonging to the technical field of the microscope. The collecting mirror comprises a collector lens, a diaphragm piece, an aperture mechanism and a regulating rod plate, wherein the diaphragm piece is stacked along the optical axis direction of the collector lens and fixedly installed on the regulating rod plate; the aperture mechanism is sheathed at the periphery of the collector lens; and sponge cushion blocks are arranged in the connecting part of the diaphragm piece and the regulating rod plate and in the gaps between the collector lens and the aperture mechanism. The collecting mirror can carry out observation which is finer than dark field observation, and the collecting mirror has the characteristics of stability in performance, comfort, no light leak and the like.

Description

technical field [0001] The invention relates to the technical field of microscopes, in particular to a condenser lens of a microscope. Background technique [0002] Currently, objective lenses or condenser lenses mounted on microscopes and the like have been used not only for common bright-field observation but also for dark-field observation. However, when a condenser is used for dark field observation, due to problems such as looseness and light leakage of the condenser, the circular beam is uniformly irradiated from the periphery of the optical system, not only cannot detect parts with microscopic defects and foreign objects, but also cannot detect the direction Sexual defects. Contents of the invention [0003] The object of the present invention is to provide a condenser lens of a microscope, which can perform finer observation than dark field observation, and has the characteristics of stable performance, comfort, and no light leakage. [0004] In order to solve th...
