SANTA ROSA, CA – Cal Sensors announces the launch of PIRE^Plus, a high-output, high-pulse rate emitter that can be pulsed as a source of blackbody radiation for near-to-far infrared applications at 180Hz with 50% modulation depth. With a pulsing speed 18 times faster than alternative technologies, the PIRE^Plus maximizes signal to noise performance, expanding the measurement dynamic range and resolution for trace gases with very low parts per million. The solid state emitter offers high output (4×10^-2 watts/cm² at 1 inch from filament) and includes integrated drive electronics.

The high pulse speed of the PIRE^Plus high-output, high-pulse speed emitter allows for more sensitive and accurate readings of materials with lower parts per million concentrations.

The PIRE^Plus is well-suited for a variety of applications, including industrial and medical gas analysis, environmental monitoring, process control instrumentation, spectroscopy and plastics sorting.  The pulsable emitter offers enhanced signal-to-noise ratio, is compatible with a wide range of detector technologies, and comes in an industry-standard T0-5 header package.

“The PIRE^Plus provides unique performance opportunities to the marketplace,” explains Brian Elias, Director of Engineering at Cal Sensors. “Whereas alternative technologies pulse at roughly 10 Hz with 50% modulation, the PIRE^Plus features a pulse speed that is 18 times faster – allowing users to obtain accurate readings of materials with much lower parts per million concentrations. Furthermore, the PIRE^Plus provides this high pulse speed without the added expense of having to build in optical choppers or mechanical modulators as is often done with incandescent bulb emitters and covers a much wider spectrum than high-pulsing IR LEDs which focus on only very narrow bandwidths.”

The radiating element in PIRE^Plus is an ultra-thin specially designed metallic foil configured to ensure 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. PIRE^Plus emitters are designed to operate at a rated maximum foil temperature of 1000° Kelvin and are offered with a standard integrated reflector to provide near collimated and uniform radiation output. A variety of elliptical reflectors with varying focal lengths are also available for coupling into optical fibers and other applications.

The PIRE^Plus comes with integrated drive electronics in an industry standard 14 pin-dip IC package. The user-friendly drive electronics are voltage variable and allow users to select from a wide range of frequencies between 1Hz and 500Hz according to their specific application needs. A special feature of the drive electronics is the ability to provide peak pulse temperatures independent of the pulse frequency.  This ensures the highest output for any application.

Compatible with a wide range of IR detector technologies, the PIRE^Plus emitter can be paired with Cal Sensor´s new MIRA4 four-color lead selenide (PbSe) sensor that provides industry-leading sensitivity of 1.5E10 Jones in the detection of up to four distinct gases in the 1.0 to 5.5 µm infrared region. The PIRE^Plus emitter and MIRA4 detector can be purchased together as an integrated module for quick integration and efficient design and performance.
