LIGHT EMITTING DIODES 1.6¸ 4.6 mm
Model LED29-TEC
2.9 mm 8 mW
•Light Emitting Diodes LED29-TEC are designed for emitting at a spectral 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 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 in two
recommended here regimes (Quasi-CW and Pulsed).
