Custom Glass optic

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. Slits of widths: 1-1000 mm extend across the whole substrate. Substrate Diameter: 25.4 mm (1.0 inch). Thickness: 1.5mm. Slit width Tolerance: 5%. Optical density: 3. We can accept customization, from prototype to mass production. If you have different requirements or designs, please feel free to contact us for more details.
