MIL-F-21424A
FILTERS, POLARIZING (FOR OPTICAL INSTRUMENTS)
Organization:
NAVY - OS - Naval Surface Warfare Center (NSWCIHEODTD)
Year: 1975
Abstract: This specification covers polarizing filters for use in optical instruments. Intended Use: Optical polarizing filters may be used singly, in an optical instrument or with the unaided eye, to reduce the intensity of light reflected from a spectral surface or due to haze. They may also be used in pairs as a light attenuator (variable-density filter) by rotating one filter with respect to the other so that the light intensity may be varied from maximum to virtual extinction.
