v 1.0 12.02.2014
Description
LED21 series are fabricated from narrow band-gap GaInAsSb/AlGaAsSb heterostructures lattice matched to
GaSb substrate. This Mid-IR LED provides a typical peak wavelength of 2.15 µm and optical power of
typ. 1 mW qCW. It comes in TO-18 package a with a glass window.

• D-51
• mD-1c
• mD-1p
We recommend to use Quasi Continuous Wave (qCW) mode with duty cycle 50% or 25% to obtain
maximum average optical power, and short Pulse mode to obtain maximum peak power.
CW (continuous wave) mode is NOT recommended!
