Cal Source SHA-Series infrared (IR) emitters are designed to be used as Steady State (DC) emitters of blackbody radiation.

The radiating element in the Steady State emitters is a coiled filament of a Cal Sensors specific material with a specialized coating to give an
emissivity of 0.70. Radiated output closely emulates a blackbody in spectral distribution. SHA-Series emitters are designed to operate at a rated filament temperature of 1170° K.

SHA-Series emitters are offered in several models with specific filament diameters and number of coils to provide the desired input/output power at a filament temperature of 1170 ° K.

The new emitters include a parabolic reflector to provide near collimated and uniform radiation output. These packages do not include windows.
