Fluorite crystal lens

Pure fluorite crystal lenses


Pure fluorite crystal lenses represent the pinnacle of optical excellence, offering Kowa enthusiasts an unparalleled viewing experience. Unlike standard Extra-Low Dispersion (ED) glass, fluorite crystal minimizes chromatic aberration to an extraordinary extent. This reduction in colour fringing results in images of exceptional clarity, resolution, and contrast, elevating the overall viewing quality to unmatched heights.

Kowa factory assembling

Japanese craftmanship


Our roots are in Japan, all products are designed there and most are manufactured in our own factory in Soka, Japan. From lens cutting, shaping and polishing through to final assembly, every optic that leaves the Kowa factory in Japan must pass a series of stringent tolerance tests before it is released to the market. The pinnacle of optimal excellence is represented by PROMINAR.
