Optical interference filters use the interference effect to obtain spectral transmission are manufactured by depositing thin layers with different refractive indices onto a substrate.
Daheng offers standard and customized optical interference filters. Read more...

Circularly variable neutral density filters are designed to simplify attenuation and beamsplitting from VIS to near IR. The optical density gradually varies around a 270circle for convenient attenuation adjustment by simply rotating the filter. Attenuation is achieved by a thin Ni-Cr-Fe film, allowing these attenuators to withstand moderate laser energy as well as to act as variable beam... Read more...
