Where to Buy Neutral Density Filters

Neutral density filters are optical attenuators which have an approximately constant degree of attenuation (filter loss) in a substantial wavelength range – for example, throughout the visible spectrum or in some part of the infrared spectrum. They can be of absorbing or reflective type, depending on the required power handling capability. They are used in photography, but also in various parts of photonics and laser technology.

neutral density filters

VisiMax process neutral density (ND) filters produce a constant attenuation across a range of visible wavelengths, and are used to reduce the intensity of light by reflecting a portion of it. VisiMax ND filters transmit only a specified percentage of light equally across a range of wavelengths, enabling important performance features in a range of optical systems.
