LIGHT EMITTING DIODES 1.6÷4.6 µm
Model LED46-TEC-PR
•Light Emitting Diodes LED46-TEC-PR are designed for emitting at a spectral
range around 4600 nm. Thermocooler and thermoresistor are mounted inside 9
mm package TO-5. Heterostructures (HS) are grown on InAs substrates
•Light Emitting Diodes LED46-TEC-PR are developed for using in optical gas
sensors and medical diagnostics. Such construction gives possibility for
temperature stabilization of LED parameters. Lifetime is more then 10000 hours.
•Related products: Our standard LED Driver provides power supply of LED46-
TEC-PR in two recommended here regimes (Quasi-CW and Pulsed).
