Custom Fused Silica Optical Windows for Laser Systems - China Suppliers & Factory | UV-IR Transmission, 1-500mm Sizes
●Optical Window
✦1. Core Functions
- Environmental Isolation: Seals vacuum, high-pressure, or corrosive environments while transmitting 190nm–2.1μm light with >92% efficiency.
- Laser Resistance: Fused silica substrates withstand high-power laser damage (LIDT >10J/cm² @1064nm, 10ns) for CO₂, YAG, and femtosecond lasers.
✦2. Technical Specifications
-
Material Properties:
- Fused Silica: Thermal expansion 0.55×10⁻⁶/°C, softening point 1580°C, superior UV transmission vs. N-BK7.
-
Precision (High-Grade):

- Thickness tolerance ±0.005mm, diameter +0.01/-0.01mm, parallelism <1 arcsec;
- Clear aperture 100%, scratch/dig 20/10 (upgradable to 10/5).
-
Coatings:
- AR Coatings: Single/dual-sided for 193nm–10.6μm (e.g., 355nm, 1064nm, 10.6μm);
- High-LIDT Coatings: Compatible with >1kW CW or >100mJ pulsed lasers.
✦3. Applications
- Laser Processing: Output windows for fiber lasers to shield internal optics;
- Spectroscopy: VUV spectrometer windows for high transmission and low scatter;
- Harsh Environments: Observation windows for high-temperature furnaces or radiation-resistant sensors in aerospace.
✦4. Customization
- Non-Standard Sizes: Custom shapes (square, annular), bevels 0.3±0.2mm×45°, or edge treatments;
- Hybrid Windows: Combined with sapphire or CaF₂ for multi-band splitting or AR optimization;
- Fast Delivery: Standard orders in 5 days, special coatings/sizes <3 weeks.
