Abstract

The utility model belongs to the improvement of a microscope. A support arm of the existing microscope is provided with an incision part, or adopts a transparent component, or is provided with a lens part simultaneously, and therefore, observers can observe the upper surface of an objective table through the incision part or the transparent component so long as moving eyes from an eyepiece slightly downward to confirm the relative position of the front end of an objective lens and a sample to be observed. Thereby, the utility model avoids the defect that the observers can only observe the upper surface of the objective table by going onto the side face of the microscope; in contrast, the utility model is convenient and can also not block off light rays.

Description

Microscope

The utility model relates to a kind of microscope, and particularly the sort of eyepiece is to be separated and the relative microscope that splits by support arm with object lens.

Fig. 6 represents existing optical microscope simple in structure, base 10 is provided with illuminating catoptron 8 of sample and support arm 3, is provided with rocking handle 9 at the root near this support arm 3, in the lower vertical part of support 3, objective table 5 by horizontal supporting, but and free lifting.In addition, the top of support arm 3 is to the bending of the top of objective table 5; At the head of
