Cal Sensors has released its new low cost, broadband emitter that provides significantly higher output compared to standard steady state emitters of blackbody radiation. The radiating element in the steady state emitter is a coiled filament of a Cal Sensors specific material with a specialised coating for an emissivity of 0.70. The special filament and a new generation of reflectors, boost output efficiency. The radiated output closely emulates a blackbody in spectral distribution. The emitter is designed to operate at a rated filament temperature of 1170˚K. The new higher output emitters range in input power from 1.15 Watts to 2.1 Watts and are available in TO-5 packages. These windowless packages provide long-term stability and lifetime without spectral attenuation caused by window materials.
