Linear Variable Neutral Density Filters
May 2016Reynard CorporationRequest Info
The Linear Variable Neutral Density (LVND) filter is designed to attenuate light as the filter is translated. These filters are compatible with broadband and single-band applications. The typical wavelengths are from 375 to 2500 nm. Extended ranges from 200 nm to 15 µm are possible with specialized substrate materials. Large apertures can be achieved by translating two LVND filters in opposite directions.
