LIGHT EMITTING DIODES 1.6÷ ÷4.6 µm 4 .6 µ m Model LED46-TEC 6 µW •Light Emitting Diodes LED46-TEC 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 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 in two recommended here regimes (Quasi-CW and Pulsed).
