Thorlabs’ Ground Glass Diffuser Kit contains a selection of mounted Ground Glass. Our Ground Glass Diffusers are ideal for general purpose applications. The SM1 compatible mounts are engraved with the item number and a brief description. Ground Glass Diffusers provide an economical solution for a variety of applications requiring Gaussian diffusers. These diffusers are offered in 120, 220, 600, and 1500 grit polishes. A finer grind (e.g. 1500) provides a higher transmittance, while a coarser grind (e.g. 120) creates a greater amount of diffusion at the expense of transmission. The DGK01 Diffuser Kit includes four Ø1” mounted ground glass diffusers, with one diffuser in each grit polish, as well as a Ø1” mounted ground glass alignment disk and a metal storage box.
