Melting quartz protective window

A melting quartz protective window is an optical protection component made of high-purity silicon dioxide, characterized by the following features: 1. Excellent optical performance: It has high transmittance in the ultraviolet, visible, and near-infrared bands (typically 185nm-2.1μm), enabling clear transmission of light signals and suitability for high-precision optical systems. 2. High temperature resistance: It can withstand extreme temperature environments with a small thermal expansion coefficient, maintaining structural stability under high temperatures or temperature fluctuations, and is less likely to deform or break. 3. Strong chemical stability: It is resistant to corrosion by most chemicals and can withstand erosion from corrosive media such as acids and alkalis, making it suitable for use in harsh chemical environments. 4. High mechanical strength: With high Knoop hardness, it exhibits good scratch and impact resistance, effectively protecting internal optical components from physical damage. 5. Low fluorescence: It emits extremely weak self-fluorescence under illumination, avoiding interference with optical measurement results and being suitable for high-sensitivity optical detection scenarios.
