LED43

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.

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!
