The 52CIN glass is a high performance green background neutralizer optimized for medium light applications. Compared to the 40CN, the 52CIN offers increased light transmission and a more intense red content to provide improved color brightening. This glass is particularly well suited when greater brightening and enhancement of the target against green backgrounds is required, especially in low light. The additional orange coloring of the 52CIN provides effective contrast enhancement and more precise target detection, even in difficult lighting conditions.
