MSE PRO™ UV Fused Silica (UVFS) Flat Windows, Round Shape

Fused Silica windows are optical components made of fused quartz, possessing excellent optical performance. They find extensive applications in aerospace, military, medical, scientific research, and other fields.

These windows are typically used as protective windows for electronic sensors or detectors in external environments. They serve to separate the internal and external environments of instruments, ensuring isolation to protect internal components. They do not alter the system's magnification.

Fused quartz is a high-purity, high-temperature-melting, colorless, and transparent material with outstanding optical properties such as high transmittance, low refractive index, low dispersion, high thermal stability, and a low coefficient of thermal expansion. Fused quartz window are commonly employed as essential optical components.

Coating treatments can also be applied to enhance its transparency and anti-reflective properties. Please contact us for customized coating services.
