PULSABLE IR SOURCE

Model EF-8533

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 Zinc Selenide (ZnSe)

window. Specify either 2 lead (EF-8533-2) or 4 lead (EF-8533-4) versions.

Photo shows 2 lead version.

Key Features Include:

• Filament has uniform emitting area

• Emissivity is 0.88

• Zinc Selenide (ZnSe) window

• Operates in pulsed or steady state mode

• Industry standard TO-8 package

• Operates at peak temperature of 700°C (973°K)

• Large temperature change, AT, during pulsing
