5500-14000nm AR Coated Infrared Custom Optical Windows Description
5500-14000nm Broadband IR AR Coated Custom Optical Windows Coligh manufactures is a high-performance optical window designed for the 5.5-14μm mid- and far-infrared band. We use silicon as the substrate and combine it with multi-layer anti-reflection coating technology. This optical window significantly reduces the surface reflectivity in a wide band through customized film design and advanced coating technology, and the transmittance is increased to more than 80%.
- The average transmittance at 5.5-14μm is greater than 80%, with ultra-wide band high transmittance, supporting multi-spectral fusion detection
- We use ion beam assisted deposition technology and AR coating to optimize performance. The wide-band anti-reflection coating design covers the entire 5.5-14μm band.
- Silicon as a substrate has extreme environmental adaptability, high temperature resistance, and is suitable for steelmaking furnaces, spacecraft thermal protection, chemical industry, and marine environments
- We have strong customization capabilities, with diameters from 1mm to 1000mm, supporting planes, spherical surfaces, aspherical surfaces, and special-shaped structures;

5500-14000nm AR Coated Infrared Custom Optical Windows Applications
- Industrial manufacturing
Local overheating of high-voltage power transmission and transformation equipment, 5-14μm thermal radiation is prone to cause failures, and non-contact infrared monitoring is required, but the outdoor environment is dusty and the temperature difference is large. This optical window can be integrated into the infrared thermal imager of the inspection drone to identify hot spots of different temperature levels and resist equipment vibration and sand and dust friction caused by wind - Environmental monitoring
Among the dioxins generated by garbage incineration plants, dioxin generation is strongly related to furnace temperature and needs to be monitored in real time, but high temperature and corrosive gases corrode traditional windows. This infrared optical window can be embedded in the infrared temperature measurement system of the incinerator and tolerate acidic gases such as HCl and SO₂ - Military technology
Submarine periscopes need to transmit infrared signals of 8-14μm and shield their own thermal radiation to avoid being detected by enemy infrared satellites. This infrared optical window can be used as a periscope infrared channel window to adapt to deep-sea environments - Scientific research field
Ultrafast laser pulses require low dispersion and high damage threshold windows, but traditional materials (such as ZnSe) have large dispersion and high cost. This optical window can be used as a vacuum cavity laser exit window to facilitate laser research
