Diffuser

Light Shaping

Precision Optical Systems offers light shaping diffusers fabricated using a holographic recording process. The randomized surface structures of the holographic design allows the transmitted light to be precisely shaped. Additionally, the transmitted beam is homogenized and greatly reduces the problem of hot-spots. Depending on the angle of distribution, these diffusers will achieve between 85% and 92% transmission efficiency. Available in both elliptic and circular outputs in a variety of substrates, sizes and angles. We can custom cut to your specifications, please check with us for more details.
