Abstract
Fourteen ZnSe samples of different quality were fabricated and tested to determine the effect of specific defects, such as haze, flowering and inclusions on ZnSe absorption at 10.6 micrometer and transmission in the wavelength range 0.5 to 22 micrometer. The results show that haze, large inclusions (diameter equals 1 - 2 mm) and the sample cleaning procedure can affect the ZnSe absorption at 10.6 micrometers significantly. However, the absorption is not very sensitive to variations in surface finish or the presence of flowering and small inclusions (diameter equals 0.05 - 0.3 mm). Further, the infrared transmission in the wavelength range 2.5 - 22 micrometers did not show any appreciable variation with material quality or the surface finish, but that visible transmission around 0.55 micrometers was significantly degraded by the presence of haze and flowering.
