LIGHT EMITTING DIODES 1.6¸ 4.6 mm

Model LED46-TEC

4.6 mm 6 mW

•Light Emitting Diodes LED46-TEC are designed for emitting at a spectral range

around 4600 nm. Thermocooler and thermoresistor are mounted inside 9 mm

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

•Light Emitting Diodes LED46-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

LED46-TEC in two recommended here regimes (Quasi-CW and Pulsed).
