LIGHT EMITTING DIODES 1.6÷4.6 µm
Model LED43-TEC 4.3 µm 10 µW
•Light Emitting Diodes LED43-TEC are designed for emitting at a spectral range
around 4300 nm. Thermocooler and thermoresistor are mounted inside 9 mm
package TO-5. Heterostructures (HS) are grown on InAs substrates
•Light Emitting Diodes LED43-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: Our standard LED Driver provides power supply of
LED43-TEC in two recommended here regimes (Quasi-CW and Pulsed).
