Objective 20HP 20/0 black

The phase objective is designed to study indistinguishable or barely visible living specimens without contrast. In this case, staining microorganisms is impossible, as it leads to their death. Phase contrast makes microorganisms visible without affecting or directly damaging them. For phase contrast observations, you will need a phase condenser. The 20HP objective is associated with an annular diaphragm marked 20x or a phase contrast annular plate with a ring for the 20x objective. The 20HP model has a magnification of 20x and works best with eyepieces between 10x and 20x. Together, they form a useful microscope magnification of 200x to 400x. It is not advisable to include eyepieces of a different magnification in the system, as they will not provide a sufficiently informative image or will be excessive and offer no additional advantage. The objective distinguishes sample elements at a minimum distance of 0.69 µm. The objective has a large flat field, covering 90% of the entire visible surface, and focuses uniformly across the entire visible area. This function is well supported by digital cameras or eyepieces with a field of view of 22 mm. With a 10x/22 mm eyepiece, the field of view is 1.1 mm. The objective corrects chromatic aberrations at two wavelengths (red and blue) and spherical aberrations at one wavelength (green).
