Precision Neutral Density Filters
Omega is pleased to introduce precision neutral density (ND) filters. This new line excels at neutrality, with a tolerance of just +/- 3% of the density (at 550nm) between 400 and 900nm. Precision ND filters are available in optical densities of 0.30, 0.50, 1.0, and 1.5 and two standard sizes, 25mm diameter and 50mm square.
If your application requires more precise neutrality over a broad range of wavelengths, this new line of filters leaves conventional ND filters far behind.
