Fixed ND Filters (VIS)

Fixed ND Filters (VIS)

The Fixed Neutral Density (VIS) filter is a glass plate with a durable metallic coating that attenuates radiation over a wide spectral range. The filter consists of a vacuum coated spectrally neutral metallic alloy which can be used with white light as well as lasers. Fixed ND Filter sets include a wooden storage box. 

Custom sizes and densities are available upon request.
