Cal Sensors' MEMs Pulsed Emitter (MPE) is a broadband source of quasi-black body pulsed light that operates over the 1 to 20 micron infrared (IR) spectrum. Designed with patented, thinmembrane, thermo-resistive material, the MPE combines quality with high signal, fast pulses, and long life. With its broadband emission and low input power requirements, the MPE is well-suited to a wide variety of portable and traditional applications including Medical: respiratory measurements, capnography applications, and glucose monitoring; Environmental: greenhouse gas analysis, exhaust emissions monitoring, industrial plant leak detection; Process control: protein and fat measurements, plastics sorting, moisture content analysis, contaminant detection; HVAC: demand controlled ventilation, refrigerant monitoring; and General applications: breath alcohol testing, gas analysis, infrared spectroscopy. The MPE promotes optimizing measurement dynamic range thanks to a combination of attributes that maximize signal output while minimizing 1/f noise. This is possible due to the emitter's high pulse speed, low thermal mass, fast response, and high temperature capabilities. When paired with high performance detector technology, high measurement sensitivity and signal to noise ratio are achieved, allowing the detection of trace gases with very low parts per million. The MPE provides high pulse rates (up to 100 Hz) and modulation depth with very repeatable results. Superior signal to noise measurements can be achieved since the fast pulses maximize the sensitivity of the accompanying detector while minimizing the 1/f noise. With a pulsing speed up to10 times faster than alternative technologies, the MPE expands the potential measurement dynamic range and resolution for trace gases with very low parts per million. The MPE offers high speed pulsing without the need for a mechanical chopper. Mechanical choppers increase system costs and increase the potential for system failures.
