MAGUS 40HP 40х/0.60 Plan L phase PHP2 ∞/1.2 WD 3.5mm Objective #83439

The phase objective is aimed at studying living biological samples indistinguishable using the brightfield method. Due to staining, microorganisms die, and so the phase-contrast method is the only one that allows the examination of non-contrast biological samples. In addition to the objective, you will need a phase condenser with a 40x ring diaphragm or a phase-contrast annuli plate with a ring for the corresponding objective magnification for its operation.

The objective is designed for installation on a biological or fluorescence inverted microscope, and it will fit an infinity-corrected optical system. The parfocal distance is 45mm. Biological samples are studied in laboratory ware with a bottom thickness of 1.2mm.

It is compatible with eyepieces with magnification from 7.5x to 15x: in such a system, the useful magnification of the microscope will be from 300x to 600x. A lower magnification of the eyepiece will not provide a detailed image; magnification above the 15x threshold will not be effective since it will not provide any new information.

The objective corrects optical distortions: chromatic in red and blue, spherical in green. Distortion takes up 10% of the visible field. The large flat field works well when working with a digital camera or in a system with a 22mm eyepiece. A 10x/22mm eyepiece will provide a field of view of 0.55mm.
