Polarizing objective for studying transparent and translucent samples in polarized light. Special distortion- and strain-free lenses do not affect the study results.
Objective with 20x magnification and a maximum resolution of 0.69µm. It is designed for a microscope with an infinity-corrected optical system. The parfocal distance is 45mm. When conducting observations, a cover glass with a thickness of 0.17mm is used.
The plan achromatic objective eliminates spherical distortion in green and chromatic distortion in red and blue colors. It levels field curvature up to 90% in diameter. The objective can be conveniently combined with a digital camera and wide-field eyepieces. For example, the field of view with a 10x/22mm eyepiece will be 1.1mm in diameter. The image is equally clear both in the center and at the edges.
The objective is optimally combined with eyepieces with a magnification of 10x to 20x and forms a useful magnification of the microscope from 200 to 400x. With a magnification of less than 200x, it will not be possible to see small details, and a magnification of more than 400x will provide no new information.
