MATERIAL PROPERTIESOptical Components
The most important optical properties of a material are its internal and external transmittances surface reflectance and refractive indexe. The formulas that connect these variables in the on-axis case are presented below. TRANSMISSION External transmittance is the single-pass irradiance transmittance of an optical element. Internal
