Helioworks offers a unique steady state infrared emitter for the mid IR spectrum that operates at up to 950° Centigrade in an industry standard TO-8 package. A calcium fluoride (CaF2) window provides spectral transmission to over 9 microns. The radiometric intensity data for all of the sources were measured with a broad band thermopile radiometer having a Potassium Bromide (KBr) window. For related technical information see the TECHNICAL section. Key Features Include: Kanthal Filament with Emissivity of 0.7 Calcium Fluoride Window Internal Gold Plated Parabolic Reflector Standard TO-8 Package Inert Gas Backfill 3 Year Lifetime Electrical Specifications: Peak Voltage = 3.0 Volts DC MAXIMUM Peak Current=1.48 Amps Peak Power = 4.4 Watts Voltage measured at base of header Package temperature must not exceed 100° C
