MAGUS SFR100 APO60 Objective

The objective is designed for studies in transmitted and reflected polarized light. The special optics of the strain-free polarizing objective ensure that the birefringence comes from the sample and not the optical elements.
 
The resolution limit of a 100х/0.90 objective is 0.30μm.
The plan apochromatic objective delivers a higher degree of chromatic and spherical aberrations compared to plan achromatic objectives. Chromatic aberrations are corrected for five colors, spherical aberration for four colors, and the field curvature is corrected for 90% of the field of view diameter. Recommended for applications with high optical resolution and image clarity requirements.
 
The objective is specifically designed for the infinity-corrected tube length. The parfocal distance is 60mm. When a 10х/22mm eyepiece is used, the diameter of the field of view is 0.22mm. It is designed to be used with the sample without coverslips.
 
The lower limit of the microscope’s useful magnification, when a 100x objective is used, is 450x. Lower magnification does not allow you to distinguish the details of the specimen whose image is formed by the objective.
The upper limit of the useful magnification, when a 100x objective is used, is 900x. Higher magnification is considered "useless" as it provides no new detail in the image of the sample.
With the 100x/0.90 objective, use eyepieces with a magnification of 10x.
