The X4 ND features SCHOTT Superwhite B270 optical glass, an ultra-clear crown glass. It is manufactured by melting high-purity raw materials and then using a continuous drawing process. The result is excellent transmission in the ultraviolet, visible and infrared spectrums, as well as a high surface quality that is particularly accepting of our state-of-the-art MRC and Nanotec coatings.Our state-of-the-art multiresistant coating (MRC) is an optical coating applied to both surfaces of the glass pane to reduce reflections and increase surface durability.
Our proprietary MRC coating is structurally harder than the glass itself and the reduced reflections improve efficiency as less light is lost. Reducing reflections also improves image contrast by eliminating stray light. The real world result? Better contrast and color.
