LED34H series

Description

LED34H series are fabricated from narrow band-gap InAs/InAsSbP heterostructures lattice matched to

InAs substrate. This Mid-IR LEDs provide a typical peak wavelength of 3.40 µm, an optical power of typ.

50 µW QCW. There are different options of packaging available, as you can choose between TO-can, with

parabolic reflector (R), window (W), and containing thermoelectric cooler and thermoresistor (T).
