ND090 Neutral Density Filter - Absorptive 12.5% Transmission
Neutral Density Filter - Absorptive 12.5% Transmission for machine-vision imaging — passes 425-675nm and blocks out-of-band light for repeatable contrast on the line.
Overview [ 01 ]
ND090 absorptive neutral density filters have an optical density of 0.9, or average 12.5% transmission across the visible spectrum. These filters include identical male and female threads on either end so that they can be stacked with other ND filters to achieve various optical densities. For example, the result from stacking two ND090 filters together would be almost identical to one (ND180) filter - transmitting approximately 1.6% of visible light.
