Fused Silica Optical Window for Laser Systems, Custom 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):
·Surface flatness ‌λ/10‌ (@632.8nm), wavefront distortion ‌λ/20 per 25mm‌;
·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.

●Product Parameter
