Reynard Corporation, a global supplier of optical components and thin-film coatings announces complete customization of their Circular Variable Neutral Density (CVND) Filters. This technology 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 narrow band applications, such as lasers, to wide band applications, such as the spectrum of white light. These filters are fully customizable in optical density gradient function, transmission gradient function, substrate type, coating materials, and size to match your application requirements.
