Superpolished ZnSe Windows Windows Product Overview
The superpolished zinc selenide (ZnSe) window is a plane infrared optical component manufactured with a high-precision polishing process. It uses high-quality CVD zinc selenide crystal as the substrate, delivering high transmittance across an ultra-broad spectral range from 0.6 µm to 16 µm. It is particularly suitable for 10.6 µm CO₂ lasers and 8–12 µm long-wave infrared (LWIR) thermal imaging.
Asin Optics is a China manufacturer of ultra-smooth ZnSe windows. Compared with conventional ZnSe windows, we use advanced coating and polishing technology to achieve a surface quality of 10-5 scratch-dig, resulting in exceptionally low scatter. This laser-grade ZnSe window is mainly used as output couplers and protective windows in high-power COâ‚‚ lasers, as front protective windows for infrared thermal imaging cameras, and as protective windows in FTIR spectrometers and gas analyzers.
Superpolished ZnSe Windows Key Benefit
We specialize in custom-manufacturing super-polished Zinc Selenide (ZnSe) windows designed for applications requiring ultra-low scattering, superior surface quality, and high infrared transmission. Utilizing CVD-grown ZnSe substrates, we employ precision super-polishing techniques to achieve a surface quality of 10-5. This process minimizes scattering losses and tightly controls surface roughness, ensuring the stable operation of optical systems in CO2 lasers, infrared thermal imaging, and FLIR systems.
- Our super-polished ZnSe windows meet the US military standard 10-5 for surface quality; they exhibit ultra-low scattering loss and effectively suppress stray light from entering detectors within the infrared spectrum.
- CVD ZnSe maintains exceptionally high transmission across the 0.6–18 µm range, making it ideal for CO2 lasers, thermal imaging, and multispectral infrared systems.
- With low bulk absorption and minimal thermal lensing—combined with a super-polished surface—this material is the premier choice for high-energy laser applications, capable of withstanding continuous-wave CO2 laser power in the kilowatt range.
- We support the fabrication of windows in various shapes—including circular, square, rectangular, and custom geometries—with diameters ranging from 10 mm to 200 mm; we can also machine complex features such as steps according to your specifications.
- We achieve surface roughness levels in the nanometer and picometer ranges, with surface figure accuracy exceeding λ/10.
- For these super-polished ZnSe windows, we offer hard anti-reflective (AR) and broadband AR coatings tailored for 10.6 µm, the 3–12 µm range, or custom wavelengths; options include both standard AR and Diamond-Like Carbon (DLC) coated versions.
