Linear Variable ND Filters | Precision Light Attenuation

Linear variable neutral density filter is used to attenuate light as the filter is shifted. The filter can be used for white light as well as for lasers. A large finite aperture can be attenuated by translating two filters in opposite derections..

Linear Variable Neutral Density (LVND) Filters are precision optical components designed to vary optical density linearly across the surface, enabling fine and repeatable control of light intensity. By translating the filter relative to the beam—or by counter-translating paired elements—users can achieve smooth attenuation without introducing spectral distortion. These filters are produced with tight control over […]
