Stock Specification

Absorptive Neutral Density Filters Absorptive exhibit a level spectral transmittance in the visible region and attenuate light by absorption with minimal reflection when compared with reflective Neutral Density filters. The neutrality and density of absorptive filters are a function of the material and thickness. They are useful in light control applications, measurment instruments and exposure control in imaging. Optical Density filters exhibit an additive relationship. combining filters with OD values of 0.3 and 1.0 give a total density of 1.3
