80x magnification lens for examining the structure of metals and alloys. The accessory is designed for an infinity-corrected optical system. Its parfocal height is 45 mm.

Objects made of metals and alloys are often textured, so using the lens at normal height can damage the lens or the pattern. The planar objective is mounted at a long (1.25 mm) working distance from the specimen. Thus, it can be used safely both from the point of view of the objective itself and the examined object. This lens does not require a cover glass.

The optics of the plane-achromatic lens eliminate chromatic aberration in the case of red and blue colors, and spherical aberration in the case of green colors. Flat-achromatic lenses provide a wide working field of vision and correct its curvature by up to 90%.

The useful microscopic magnification of the 80x objective is between 400x and 800x. Its maximum resolution is 0.33 µm. For the best observation results, the objective should be combined with eyepieces with a magnification between 5x and 10x.
