Thorlabs’ Diffuser Kits each contain a selection of mounted N-BK7 Ground Glass or Engineered Diffusers. Our N-BK7 Ground Glass Diffusers are ideal for general purpose applications, while our Engineered Diffusers offer much more controlled diffusion in various distribution patterns. The diffusers in each kit are encased in SM1-threaded mounts, and are engraved with the item number and a brief description.
N-BK7 Ground Glass Diffusers
N-BK7 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) allows higher transmission, while a coarser grind (e.g., 120) creates a wider diffusion pattern 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.
Engineered DiffusersTM offer numerous advantages over traditional diffusers, providing unmatched control over light dispersion patterns and high transmission efficiency. These diffusers are transmissive from 380 - 1100 nm, and produce square, circular, and line distribution tophat patterns with a 90% transmission efficiency. The EDK01 Engineered Diffuser Kit includes five Ø1" mounted diffusers, with one diffuser for each intensity profile, and a metal storage box.
