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...
