  • Instrumentation LSCX110 laser modules are highly reliable fiber optic light sources operating in the 1300 nanometer band. The internal semiconductor lasers are based upon InGaAsP buried heterostructure (BH) technology and fabricated by the Metal Organic Vapor Phase Epitaxy (MOVPE) process, resulting in long lifetimes and modest threshold currents. LSCX110 packages include a photodiode for monitoring the laser output, a thermistor for monitoring laser heatsink temperature and a Peltier effect thermoelectric cooler (TEC). A heatsink mounting flange is incorporated into the base of the 14 pin “butterfly” package and a “bullhorn” type flange is used on the 14 pin DIL package. 5963-5308E (1/95)
