Cal Source™ SVF-series infrared (IR) emitters are designed to be used as pulsable sources of blackbody radiation.
The radiating element in the pulsable emitters is an ultra-thin Cal Sensors specific metallic foil configured so that radiation from both sides of the heated foil is efficiently directed out of the package along the optic axis. The foil material has an emissivity of 0.88 and closely emulates a blackbody source in spectral distribution. SVF-series emitters are designed to operate at a rated maximum foil temperature of 1000° Kelvin.
Standard SVF-series emitters are offered in sealed TO-5 or TO-8 packages in a variety of foil thickness and width.
Several standard window materials are available to tailor the output to specific wavelength ranges of interest.
SVF-series emitters are offered with an integral reflector. Standard parabolic reflectors provide near collimated and uniform radiation output. A variety of elliptical reflectors with varying focal lengths are also available for coupling into optical fibers or other applications.
