LIGHT EMITTING DIODES 1.6÷ ÷4.6 µm 4 .6 µ m Model LED46 •Light Emitting Diodes LED46 are designed for emitting at a spectral range around 4600 nm. Heterostructures (HS) are grown on InAs substrates. The output emission can be modulated by current flowing in a forward direction. •Light Emitting Diodes LED46 are developed for using in optical gas sensors and medical diagnostics. They have stable output power and lifetime more then 10000 hours. •Related products: Our standard LED Driver provides power supply of LED46 in two recommended here regimes (Quasi-CW and Pulsed).
