Pire Plus 225pxWe offer Opto Diode's pulsable thermal emitters. Two families of devices are available:-


  • SVF-series - Standard pulsable emitters
  • SPF-series - Fast pulsable emitters


SVF-Series infrared (IR) emitters are designed to be used as pulsable emitters of blackbody radiation. The radiating element in the pulsable emitters is an ultra-thin Opto Diode 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.


Standard SVF-series emitters are offered in sealed TO-5 or TO-8 packages in a variety of foil thicknesses and widths along with a choice of window materials to tailor the output to specific wavelength ranges of interest. SVF-series emitters feature an integral parabolic reflectors providing near collimated and uniform radiation output. A variety of optional elliptical reflectors with varying focal lengths are also available for coupling into optical fibers or other applications.


SPF-series emitters are designed fast pulse rates of up to 180Hz with 50% modulation depth.


The PIRE+ features the 40101 (SPF220-5M2) high-speed infrared emitter together with a driver PCB assembly and heatsink.  PIREis intended to offer users a convenient fast-pulsed source of blackbody radiation for development and product evaluation. The solution is offered as a 3-item PIRE+ kit and also pre-mounted on an evaluation board as the PIREEVB.
