MAGUS 40HP 40х/0.60 Plan L phase PHP2 ∞/1.2 WD 3.5 mm lens - MAGUS

The phase objective is aimed at studying indistinguishable living biological samples using the bright field method. Due to staining, microorganisms die and therefore the phase contrast method is the only one that allows the examination of biological samples without contrast. In addition to the objective, you will need a 40x ring diaphragm phase condenser or an annular phase contrast 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 will adapt to an optical system at infinity. The parfocal distance is 45 mm. Biological samples are studied in laboratory equipment with a bottom thickness of 1.2 mm.

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

The lens corrects optical distortions: chromatic in red and blue, spherical in green. The distortion occupies 10% of the visible field. The wide, flat field works well when working with a digital camera or in a 22mm eyepiece system. An eyepiece of 10x/22 mm will provide a field of view of 0.55 mm.

When working on the MAGUS Bio V300 inverted biological microscope, it is necessary to purchase an additional phase contrast slider, MAGUS SPH1.
