Customizing the company’s circular variable neutral density (CVND) filters is a technology that is best used in high quality optical systems to change the intensity of light from 100% to less than 0.1%. As the filter rotates, the beam intensity is modified due to the density variation of a gradient metallic coating around the filter. Used from the UV to the far infrared, density neutrality can be achieved for narrowband to wideband applications. The filters can be made on a variety of substrates including BK-7, fused silica, ZnSe, and Ge. The typical coating material is a nickel variant for room temperature, low-power applications.
