20-10 Scratch / Dig Optical Windows Datasheets

Optical Windows -- BK7
from Dayoptics, Inc.

Windows are applied to isolate different physical environments while allowing light to pass through.When selecting windows,it ’s impossible to consider materials, transmission, scattering, wave front distortion, parallelism and resistance to certain environment. Dayoptics offer all kinds of... [See More]
