LIGHT EMITTING DIODES 1.6¸ 4.6 mm

Model LED29-TEC-PR

•Light Emitting Diodes LED29-TEC-PR are designed for emitting at a spectral

2.9 mm 8 mW

range around 2900 nm. Thermocooler and thermoresistor are mounted inside 9

mm package TO-5. Heterostructures (HS) are grown on InAs substrates

•Light Emitting Diodes LED29-TEC-PR 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: LED29 can be used in optical pair with our photodiodes

PD36. Our standard LED Driver provides power supply of LED29-TEC-PR in

two recommended here regimes (Quasi-CW and Pulsed).
