An infrared or IR coating can be applied to a variety of IR substrates like Silicon, Germanium, Zinc Sulfide, Zinc Selenide and Chalcogenides to achieve desired spectral characteristics.
Here’s a graph showing the transmission characteristics of typical IR optics.
IR Beamsplitters and Coatings for Emissions Monitoring
EMF coats large optics up to 108” diameter with IR coatings for Near, Mid and Far IR, on a variety of IR substrates like silicon, germanium, zinc sulfide, zinc selenide and chalcogenides. Our proprietary PE-CVD technique for diamond-like coating (DLC), creates exceptionally durable SWIR – LWIR coating solutions to MIL-Spec on virtually all IR substrates. Our ISO Certified facilities at both Ithaca and Rochester, NY locations enable us to shorten lead times with 26 vacuum coating chambers.
With emissions monitoring for air quality, powder, dust and gasses, IR-based technologies are still in heavy use for FTIR monitoring. The important detection of pyroelectric, thermopile, lead selenide (PbSe) lead salt (PbS) and MerCad Teluride (MCT) at power plants and refineries, as well as carbon monoxide and carbon dioxide identification in emission and process monitoring is an ongoing process. The importance of this emission data and early detection of issues is key to ensuring clean air and water is available to all people.
Extractive FTIR monitoring removes gas from a smoke stack or duct, filters out particulate matter, and runs the gas through a remote sample location for real time FTIR spectrometer testing. FTIR spectra testing of emissions have been in play since the late 90’s in order to identify concentrations of CO and CO2.
In order to avoid costly fines from EPA standards non-compliance or downtime for refining, hydrocarbon processing and chemical processing, continual monitoring is essential. Complex analyzer systems today are able to process emission samples for ten elements simultaneously. The IR coatings and filters made by the divisions within Omega Optical Holdings allows instrument designers to obtain the exact dimension, flatness or curve and specific wavelength required for testing and to drop into the instrument for high volume ease of build for monitoring or sensing applications.
Better Together. Our partnerships with the Divisions at Omega Optical Holdings allow us to support even wider needs for FTIR emissions monitoring by creating very large to very small IR flat and curved optics.
If you are a manufacturer of IR-based emissions testing technologies, we encourage a conversation with us, or one of our partners today.
