Optical Windows

Optical Windows are high-performance, flat optical components designed to protect sensitive optical systems, detectors, or instruments while maintaining unobstructed light transmission across specific wavelength ranges.

When selecting an optical window, key parameters must be prioritized, including material grade, light transmittance, transmission band, surface geometry, finish quality, and parallelism tolerance—all of which directly impact the window’s performance in your optical system.

Our visible-light optical windows are engineered specifically for the 350–700nm spectrum. Designed to shield electronic sensors, detectors, and other sensitive optical components from light saturation and damage, these windows deliver uncompromised protection while maintaining the system’s original magnification and imaging fidelity. Ideal for imaging systems and protective displays across industrial monitoring, environmental testing, and precision instrumentation applications, they strike a perfect balance between durability and optical clarity.

At AOS Optics, we offer both uncoated and coated window options to meet diverse application needs. Our double-sided broadband anti-reflection (AR) coatings effectively minimize surface reflectivity and maximize light transmittance. Custom coating options are available for three core wavelength ranges: VIS (350–700nm), NIR (600–1100nm), and SWIR (900–1700nm)—tailored to your exact optical design requirements.
