Planachromatic lens with 20x magnification, 0.40 aperture with DIN mount. The obtained images are characterized by the removed chromatic aberration in the range of green and red light and spherical aberration in the range of yellow-green light. In addition, the image is adjusted for the curvature of the field. This type of lens also compensates for the spherical aberration of the optical system, providing a sharp, flat image throughout the field of view. The properties of plano-achromatic lenses are particularly beneficial for photomicrography.
