                     Absolute Reflectance Measurement of Mirrors
                     The reflectance of mirrors used in telescopes, lasers, and some other devices is extremely important because it serves as a
                     factor in determining their performance. The total light reflecting off of a sample can be composed of a specular compo-
                     nent and a diffuse component. For mirrors, the specular reflectance is the reflectance component of significance. In   Options Used for Measurements
                     addition, reflectance measurements can be made as relative to the reflectance of a background material or as absolute.
                     Absolute values of specular reflectance are determined by use of an absolute reflectance measurement (ASR) accessory. The   ISR-1503 Integrating Sphere  ASR-3105/3112/3130/3145    Variable Angle Measurement
