Optical Slit/Pinhole on Glass

Optical Glass 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, pinhole array, slit array etc including mounted and unmounted.

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

Slits of widths: 1-1000 μm extend across the whole substrate, or custom slit length

Substrate Diameter: 25.4 mm (1.0 inch)

Thickness: 1.5mm

Slit width Tolerance: ±5%

Optical density: 3
