ABSTRACT:
A wide band adjustable Brewster angle polarizer having a pair of dielectric elements adjustably mounted within a housing. A dial micrometer is operably attached to the means for adjusting the angular relationship between the normal to the dielectric material and an incoming beam of unpolarized light. The micrometer is calibrated in direct relationship between the wavelength of the incoming beam of light and the establishment of a Brewster angle between the normal to the dielectric material and the incoming beam. Thereby, by proper selection of the dielectric material, light ranging from the ultraviolet to the infrared range of the optical spectrum can be quickly and reliably polarized.
