Circular Step Neutral-Density Filter -- CSND-1-100.0M
from CVI Laser Optics

Circular step neutral-density filters are used for calibrating illumination systems from 370 nm to 2600 nm. The filter consists of a spectrally flat neutral density metallic coating deposited on one surface of a circular glass substrate. The density variation takes place in discrete steps as the...
