Custom Fused Silica Optical Windows for Laser Systems - China Suppliers & Factory, UV-IR Broadband Transmission

ALHAZEN's fused silica optical windows are engineered for exceptional UV-IR broadband transmission, making them ideal for laser systems operating in demanding environments. These high-performance windows, offered by our China-based factory, provide outstanding thermal stability and low expansion characteristics. Customizable in diameters ranging from 1 to 500mm, they feature a precise thickness tolerance of ±0.005mm and achieve λ/10 surface flatness. As leading suppliers in the industry, we ensure that our products meet the rigorous needs of high-power lasers and vacuum chambers, perfect for applications in harsh conditions

Product Detail

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
