Abstract:

The technical problems of determining the best methods for building the optical feedback based light source have been solved through procurement of the optimal components and development of adequate design techniques. The detectors that have been selected exhibit good thermally stability at 660nm wavelength. The light emitting diodes LEDs are elliptical devices with peak output of 660nm and a half power bandwidth of 25nm. These are the same detectors and basically the same light source as presently used in the Sea Tech transmissometers except in chip form.
