Optical sources ppt
WebOptical output from a source is measured in radiance (B). Radiance is defined as the optical power radiated into a solid angle per unit emitting surface area. Radiance is specified in Watts/cm2/Steradian. Radiance is important for defining source to fiber coupling efficiency.
