Optical Slits on Glass

Optical Slits on Glass

Optical Slits are widely used for entrance and exit slits in optical instruments and systems, including spectrophotometers, line spread functions, masking and in a wide range of imaging and alignment applications. We also manufacture various metal slits and pinholes, including mounted and unmounted.

Walthy optical slits are photo-etched on a chromium-coated optical glass substrate.
