•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).
