LIGHT EMITTING DIODES 1.6¸ 4.6 mm

Model LED20-TEC

2.05 mm 1.1 mW

•Light Emitting Diodes LED20-TEC are designed for emitting at a spectral range

around 2050 nm. Thermocooler and thermoresistor are mounted inside 9 mm

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

•Light Emitting Diodes LED20-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: LED20 can be used in optical pair with our photodiodes

PD24. Our standard LED Driver provides power supply of LED20-TEC in two

recommended here regimes (Quasi-CW and Pulsed).
