Our Absorptive or Reflective Neutral Density Filter products are popular in the market. Neutral Density Filter belongs to Polarization Optics, as a kind of core Optical Elements of Laser Components, is including Neutral Density Filter Absorptive and Neutral Density Filter Reflective. Neutral Density Filter are used to attenuate light over a wide spectral range by coating a durable metallic film. The Polarizing Filter can be used with white light as well as with lasers. It is a kind of Optical Filters that reduces or modifies the intensity of all wavelengths, or colors, of light equally, giving no changes in hue of color rendition.

Reflective neutral density filter, using the principle of thin film interference, part of the light through, and the other part of the light reflection. Absorption neutral density filter, generally refers to the material itself or in the material mixed some elements, for certain wavelengths of light absorption effect, and in other wavelengths of light are not or little affected. Generally, the Laser-damaged Threshold of absorbent neutral density filter is lower.
