Pulsable IR Source
HelioWorks, Inc. offers a unique pulsable infrared emitter with three (3) radiating elements that can be addressed individually (4 lead package), or in total (2 lead package). It can operate in pulsed or steady state mode at a peak temperature of 700°C (973?K) in an industry standard TO-8 package with a Calcium Fluoride (CaF2) window. Specify either 2 lead (EF-8532-2) or 4 lead (EF-8532-4) versions. Photo shows 4 lead version.
