The new 47CIHC glass is the next generation of our best-selling Pilla glass. It builds on the success of the original 50RHC and incorporates the latest IR technology. The addition of red tint to the lens intentionally attenuates the color spectrum, which greatly improves target acquisition in medium light conditions. This medium-bright glass is ideal for situations where the light is filtered by clouds and has a natural, yellowish tint - as opposed to gray, cloudy conditions. It offers an outstanding combination of color accuracy and contrast to ensure optimal visibility in a wide range of conditions.
