LIGHT EMITTING DIODES 1.6÷4.6 µm
Model LED46-PR
•Light Emitting Diodes LED46-PR 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-PR 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-PR in two recommended here regimes (Quasi-CW and Pulsed).
