Contrast enhancement filters
are able to achieve a higher level of contrast by permitting only certain wavelengths of light from a display device to pass through. This enables display readability even under challenging conditions.
SCHOTT’s new IR filter glasses VG20 and BG60 - BG64
are designed to perform in difficult environments and deliver extraordinary image quality for reliable performance, in surveillance cameras, for instance.
Some optical filter glasses
are used for IR light protection due to their high blocking and angle independence, or as IR pass filters that block visible light.
