ND Filters

Neutral density filters are very useful in a variety of applications where a precise and known beam attenuation is needed. The absorbing glass type ND filters may be stacked for additive attenuation. Low power YAG laser filters are optimised with precisely stated densities at 1064nm. The YAG ND Filters are for low power applications only and a damage threshold is not specified or guaranteed.

The variable reflective neutral density filters provide continuous variation of the attenuation of an optical beam. They are useful for setting the required power level in both experimental and production systems. The attenuating film is an alloy with highly neutral reflective properties over the visible spectrum. The film is deposited in a continuously variable thickness over an angular range of 330 degrees of rotation of the disc. This provides a density variation from 0.04 to an optical density of 2.7. Both the BK7 and synthetic fused silica have a central hole for ease of mounting. The two sizes cover most applications.
