80-50 Scratch / Dig Neutral Density Filters Datasheets

0.1 OD, 79.43% transmission, 25.0 mm Unmounted, Absorptive Neutral Density Filter -- 010ABND-25
from Andover Corporation

With their ability to minimize back-reflections and scattered light, absorptive neutral density (ND) filters are ideal for calibration. In contrast to the metallic type, absorption-type filters achieve their optical density by absorbing light within the substrate. For this reason, thickness is a key... [See More]

Absorptive Neutral Density Filter -- ANG-10
from CVI Laser Optics

Absorptive ND filters provide an alternative to metallic ND filters. The neutrality of the filter is a function of material and thickness. Since there can be large variations between glass melts, actual thickness and glass material may vary in order to guarantee optical density. [See More]
