Circular variable neutral-density (CVND) filters from Reynard Corp. are fully customizable in optical density gradient function, transmission gradient function, substrate type, coating materials and size.
The filters may be used in high-quality optical systems at UV to far-infrared wavelengths to change the intensity of light from 100 percent to less than 0.1 percent. They are intended for narrowband applications, such as lasers, and wideband applications, such as the spectrum of white light.
Gradient function can be supplied from 45° to 360° of rotation. The substrates range in diameter from 1 to 8 in.
