v 2.0 24.11.2014
Description
LED43 series are fabricated from narrow band-gap InAsSb/InAsSbP heterostructures lattice matched to InAs
substrate. This Mid-IR LED provides a typical peak wavelength of 4.15 µm and optical power of
typ. 0.01 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!
