Problems solved by technology

[0003] The technical problem to be solved by the present invention is: in the prior art, the eyepieces and objective lenses of the microscope have small apertures, the light rays shining on the object to be measured are already very weak when entering the eyes of the observer through the objective lens and the eyepieces, and the measured Objects are generally extremely small objects, so it is difficult to observe the measured object clearly and accurately, resulting in errors in the measurement results, and it is also not conducive to the eyesight of the observer

Abstract

The invention is a microscopic object-lens brightening method, placing a microscopic lighting installation under the object lens, the lighting installation composed of base, drawtube part and lighting part, the drawtube part composed of adjusting, middle and front drawtubes, the lighting part set on top of the front one and able to adopt LBD connected with power supply through the lead. It can adjust the intensity of the light which enters the observer's eye through the object lens and ocular, and clearly and accurately observe, reducing the error of the measuring result and meanwhile beneficiail to protect the observer's sight.

Description

Technical field: [0001] The invention relates to a microscope, in particular to a method for brightening a microscope objective lens. Background technique: [0002] In the prior art, when the object to be measured is placed under the objective lens of the microscope, the observer observes the object to be measured through the eyepiece and the objective lens. Since the eyepiece and the objective lens of the microscope are small in area, the light shines on the object to be measured and enters through the objective lens and the eyepiece. The eyes of the observer are already very weak, and the measured objects are generally extremely small objects, so it is difficult to observe the measured object clearly and accurately, resulting in errors in the measurement results, and it is also not conducive to the observer's vision. Invention content: [0003] The technical problem to be solved by the present invention is: in the prior art, the eyepieces and objective lenses of the micr...
