We supply liquid crystal based variable Neutral Density Filters from LC-Tec.
Although all LCT's Fast Optical Shutter models allow gray-level operation, the innovative and patented PolarView®-eND(NBf2.0)-IQUV(100µm) technology is specifically designed for operation as a variable Neutral Density (ND) filter.
LCT's PolarView®-eND(NBf2.0)-IQUV(100µm) replaces multiple filters with a single device which can be switched between F2 and F12 and is designed for flat spectral response and low angular dependence. As a result PolarView® filters offer uniquely uniform angular transmittance properties together with small color shift and are ideal for professional still and movie cameras as well as many commercial and industrial applications.
The optical density of the PolarView®-ND filter is controlled electronically without any moving parts. The device is completely analog and fast switching from one setting to another enables instant adjustment in response to changing light conditions.
The standard PolarView®-eND(NBf2.0)-IQUV(100µm) is designed to match full frame digital SLR image sensors with an outline of 44x33mm² and there is a large area version, PolarView®-eND(NBf1.5)-IQUV, which is 4" x 5.65".
