Description
Neutral density (ND) reflective type filters of 1’’ (25.4 mm) size with optical density that varies from 0.1 to 2.5 are available.
Neutral density filters of Corning 7059 glass provide spectrally uniform attenuation from 400 nm to 2000 nm. The reflective coatings enable to reduce thermal effects when these filters are used with moderate power lasers.
