Description
Meiji Techno's TC Plan Objectives are made with extra-low-dispersion glass and utilizes advanced multilayer anti-reflection coatings. The technology used in designing and creating the TC Plan objective lenses result in an objective with higher image contrast, higher resolving power, wider field of view, improved flatness of field, and a sharp image with minimum flare and ghosting. Objectives are color corrected for chromatic aberration in the red and blue regions of the spectrum and offer an exceptional flat field of view.
