Fused Silica Circular Window

Product Overview
Fused silica circular windows are optical elements made from high-purity fused silica. They are widely used in aerospace, military, medical, and scientific research fields. As protective windows for electronic sensors or external environmental detectors, they effectively isolate the internal components of instruments from the external environment, protecting sensitive devices in optical systems. Fused silica windows offer excellent optical properties, including high transparency, low dispersion, high thermal stability, and low thermal expansion coefficient, making them suitable for optical systems that require high stability and performance.

Key Features

• High Transparency: Fused silica windows have excellent transmittance, especially in the ultraviolet, visible, and near-infrared wavelength ranges.
• High Thermal Stability: Fused silica has excellent thermal stability, maintaining superior optical performance in high-temperature environments.
• Low Thermal Expansion Coefficient: Its low thermal expansion coefficient ensures no deformation due to temperature changes, making it suitable for applications in varying temperature conditions.
• Low Dispersion: The low dispersion property ensures that light passing through the fused silica window does not experience noticeable chromatic aberration or distortion.
• High Laser Damage Threshold: Ideal for high-power laser systems, fused silica windows have a strong resistance to laser-induced damage.
• Precision Processing: Manufactured using precise processing and polishing techniques to ensure high surface quality and dimensional accuracy.
• Coating Options: Fused silica windows can be coated to enhance optical performance and anti-reflection capabilities, catering to various optical needs.

Applications

• Optical Instruments: Used in various optical instruments as protective windows or isolation barriers for optical sensors.
• Laser Systems: In high-power laser systems, fused silica windows provide high transmission and resistance to laser damage.
• Aerospace and Military: Widely used in aerospace and military applications as equipment protective windows, shielding devices from extreme environmental conditions.
• Research and Medical: Used in scientific research and medical devices, especially in high-precision optical measurements and laser treatment systems, providing high stability and precise optical performance.
