Product Description

A neutral density filter (ND filter) is a light filter that decreases the intensity of light without changing the relative spectral distribution of the energy. An ND filter is used to attenuate the spectrum from UV to IR. So light can be attenuated by rotating or shifting the filter. The ND filters are wide applied in many kind of optical system.

Fixed ND flters are used to attenuate light over a wide spectral range by coating a durable metallic film. These filers can be used for white light as well as for lasers.
