Description
Summary:A near-Lambertian diffuser for the infrared wavelength of 10.6 microm that operates in both the transmission mode and the reflection mode has been made. The diffuser is a porous sodium chloride window with the physical advantages and disadvantages of sodium chloride as an optical material. It is simple to manufacture because of the water solubility of the salt. The bidirectional scattering distribution function is nearly flat for all scattering and incidence angles. In addition, the diffuser effectively depolarizes the scattered radiation.
