ELECTRONICS: Cal Sensors announces the launch of PIREPlus, 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 percent modulation depth. With a pulsing speed 18 times faster than alternative technologies, the PIREPlus 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 W/cm2 at 1 inch from filament) and includes integrated drive electronics.
The PIREPlus 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 radiating element in PIREPlus 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. PIREPlus emitters are designed to operate at a rated maximumfoil temperature of 1000 degree 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 PIREPlus 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 1 and 500 Hz 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 PIREPlus 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 PIREPlus emitter and MIRA4detector can be purchased together as an integrated module for quick integration and efficient design and performance.
The PIREPlus represents the latest generation of PIRE pulsable emitters that Cal Sensors officially launched at booth 2600 of the SPIE-sponsored Photonics West exhibit held Jan. 26-28 in San Francisco, CA. Cal Sensors exhibited a full line of innovative IR detector and emitter technologies at the event.
