Transmission of Silicon and Germanium in the Infrared at Reduced Temperatures
Abstract
Both silicon and germanium are widely used as transmissive elements in the infrared region of the spectrum. Both materials are typically used in applications where significant temperature ranges exist. In this work we report transmission in the wavelength range of 1.39 to 22 μm and in the temperature range of room temperature (25 °C) down to -100 °C for silicon and germanium samples of various resistivities. The data presented indicate an orderly change in transmission with decreasing temperature for the various sample resistivities. Absorption coefficients are calculated from the transmission data.
