Single-Sided Ground Glass Diffusers — HYD Series
From $21 USD
Request a quoteProduct description
HYD diffusers use N-BK7 optical glass, as specified by every listed model. One side is ground and the reverse side is polished.
The eight standard models combine 25.4 mm or 50.8 mm diameter with 120, 220, 600 or 1500 grit. They are 2 mm thick and uncoated.
Coarser 120 / 220 grit gives broader scattering with lower transmission; finer 600 / 1500 grit gives less diffuse scattering and higher transmission. The source describes use where a Gaussian diffuser is needed.
Schematic
Dimensions in mm unless otherwise stated.
For the same grit, double-sided ground glass has a larger scattering angle and lower transmission than single-sided ground glass. Align the diffuser according to the application; the ground surface is placed away from the light source as described by the source.
Other coating versions are custom inquiries, not additional standard models. Illustrations are reference views, not machining drawings.
