LED21Sr & LED21SrTO8TEC

Series LED21Sr - Optically Immersed 2.15 µm LED

PLEASE NOTE: All IR LED specifications are subject to change without notice.

led package

LEDs are fabricated from III-V heterostructures grown onto InAs substrates. Optical immersion of lens with flip-chip devices enables three to five fold increase of output power.
