Why Infrared?
What is special about infrared light?
With visible light, we can see the color of an object. By analyzing reflected or transmitted infrared light, we can “see” the chemistry within. NIR in particular can be used to identify and measure organic materials, plastics, and the presence of water.
Currently, NIR is used in industrial environments to sort plastic or analyze feed quality. In the lab, new applications are continuously being developed and may soon find their way to commercial and consumer applications.
The Mid Infrared spectrum ranges from 3 to 8 microns. Here quantitative gas sensing is possible as a result of absorption bands. An important example is carbon dioxide, absorbing at 4.3 microns.
The possibilities are endless.
Light Detection
The use of NIR light is only possible if it can also be detected. New NIR detector technologies are being developed, making the NIR spectrum more accessible than ever.
New applications are emerging with the proliferation of InGaAs and extended InGaAs cameras. The development of high-efficiency, low-cost detectors covering the visual to three micrometer spectrum brings within reach sensing opportunities previously impossible. A matching source allows future analysis platforms to fully leverage the new detectors.
Light Generation
Higher quality broadband NIR light results in a higher quality spectrum, containing more reliable and actionable information.
Traditional IR spectroscopy uses tungsten sources not suited for embedded systems. LEDs, exceptionally performing in the visual ban, are ineffective in generating broadband illumination and at longer wavelengths become increasingly inefficient.
4K-MEMS emitters cover the entire NIR/SWIR electromagnetic spectrum, and extending into the visible and mid infrared, bridging the gap between visual LEDs and longer wavelength thermal emitters.
