LIGHT EMITTING DIODES 1.6÷
÷4.6 µm
Model LED23-PR
2.35 µm 0.8 mW
•Light Emitting Diodes LED23-PR are designed for emitting at a spectral
range around 2350 nm. Heterostructures (HS) are grown on GaSb
substrates. The output emission can be modulated by current flowing in
a forward direction.
•Light Emitting Diodes LED23-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: LED23-PR can be used in optical pair with our
photodiodes PD25. Our standard LED Driver provides power supply of
LED23-PR in two recommended here regimes (Quasi-CW and Pulsed).
