Ground glass diffuser is an optical element to weaken or scatter strong light. It can protect highly sensitive measuring instrument or prevent from imaging.
The right surface of GG diffuser is ground, and the other surface is polished. Different grades of grind provide different level of scattering. A finer grind provides a higher transmittance, while a coarser grind creates a greater amount of diffusion at the expense of transmission.
The float glass substrate has excellent visible transmission and is ideal for general diffusing applications. Typical applications include use in screens, illuminator diffusion, and targets.
