Product Description
T5 Grade Polished Quartz Window (5mm Thick Fused Silica Laser Protective Sheet) Basic Product Information

Product Name: Double Side Mirror Polished High Purity Fused Silica Window (T5 Thickness for Laser Equipment)
Specification: Customizable outer diameter, standard thickness T=5mm (short name T5 material)
Surface Process: Double-sided nano-grade mirror polishing, anti-reflection AR coating optional

Main Applications

This polished sheet is made of high-purity fused silica with double-sided nano mirror finish. It features high temperature resistance, laser irradiation resistance, low hydroxyl content, strong corrosion resistance and extremely low light loss. It is mainly used as protective window for fiber and CO₂ laser equipment, as well as optical window for semiconductors, high-temperature observation and spectral instruments. Detailed scenarios are as follows:

Fiber Laser Cutting and Welding Equipment (Core Application)

Semiconductor and PV Microelectronics

Laboratory Optics and Spectral Analysis Instruments

Fine Chemical and Environmental Special Working Conditions

Core Advantages (vs Thin Quartz Sheets and Borosilicate Glass Windows)

Thick T5 Thermal Stable Structure: 5mm thick substrate with large heat capacity and fast heat dissipation, resistant to thermal deformation and cracking under high-power laser radiation, far better thermal shock performance than thin quartz.

Double-Sided Nano Mirror Polishing: Surface roughness Ra≤1nm, free of scratches, pits and bubbles with extremely low beam scattering loss and high laser energy transmittance.

Wide High-Temperature Resistance Range: Stable continuous service at 200℃~1100℃, ultra-low thermal expansion coefficient without cracking under cold-hot alternation.

Outstanding Chemical Corrosion Resistance: Withstand hydrofluoric acid, concentrated acid, alkali and organic solvents; borosilicate glass fails under HF environment.

Ultra-Low Impurity and Low Hydroxyl Content: High-purity fused silica without heavy metal dissolution, no contamination to wafers, high-purity reagents and electronic process gas.

Full-Band High Light Transmittance: Excellent UV, visible and near-infrared transmittance; customizable AR coating for 1064nm / 10.6μm laser to further raise transmittance.

High Hardness and Spatter Resistance: High Mohs hardness, no permanent scratches from slight metal spatter, reusable after cleaning.
