The illumination source employs different technologies, ranging from lamps to semiconductor light emitting diodes (LEDs) or lasers. The lamp, while straight-forward, is broad-band, bulky, and generally inefficient. The main wavelengths of interest for illumination are around 808nm, 976m, 1064nm,…...
