Andover Corporation Neutral Density Filters -Image

Neutral density filters are useful in a number of applications such as attenuators for broadband spectral sources, partial reflectors for light balancing applications and for use as neutral beamsplitters. Metallic type neutral density filters obtain their optical density by depositing a metal alloy coating onto a specific type of substrate which is determined by the wavelength region of interest. Absorbing ND filters are produced using Schott NG glass, and rely strictly on the absorptive effects of the glass to obtain the desired attenuation level.
