Abstract

The biological microscope with an aspheric lens objective which belongs to the technical field of biological microscopes comprises a base, a bent wall, a coarse hand wheel, a fine hand wheel, a lifting cylinder, an ocular lens, an ocular lens barrel, a converter, an objective lens group, an objective table and a movable light source. The objective lens group comprises an objective lens A with an aspheric lens, an objective lens A for short, an objective lens B with an aspheric lens, an objective lens B for short, an objective lens C with an aspheric lens and an objective lens C for short; andthe objective lens A is a 4X objective lens, namely a quadruple objective lens, the objective lens B is a 10X objective lens, namely a ten-fold objective lens, and the objective lens C is a 40X objective lens, namely a 40-fold objective lens. The microsope has the beneficial effects that the working distance is long, and the object is convenient to observe.

Description

technical field [0001] The invention relates to a biological microscope, in particular to a biological microscope equipped with an aspherical lens objective lens, and belongs to the technical field of biological microscopes. Background technique [0002] Biological microscopes are used to observe and study biological slices, biological cells and living tissue cultures, and are widely used in teaching and scientific research. Conventional biological microscope objective lens structure is an optical system composed of multiple glasses, the structure is relatively complex, the optical performance is poor, and the working distance of the objective lens is very short, which cannot meet the needs of people's work. The working distance of ordinary 4X objective lens is 12.8mm, the working distance of ordinary 10X objective lens is 5.7mm, and the working distance of ordinary 40X objective lens is 0.45mm. In-depth objects, causing inconvenience to users. Contents of the invention ...
