Normal Half Apochromatic Field Objective , Microscope Achromatic Objective Lens
The discrimination ability of microscope mainly depends on the objective lens. The discrimination ability of objective lens can be divided into plane and vertical discrimination ability. Objective lens is the most important optical unit that determines the basic performance and function of optical microscope.
Half apochromatic objective lens (halfapochromatic) some lenses are made of fluorspar, so it is also called fluorspar objective lens. Its performance is better than that of apochromatic objective lens, and its price is cheaper than that of compound apochromatic objective lens. The degree of corrected aberration is between achromatic and complex achromatic objective lenses, but other optical properties are similar to the latter; The price is low. It's best to use it with the compensation eyepiece.
