China Fused Silica Laser Window (WFS Series) Broadband 343-355nm UV & 1030-1090nm IR Optical Lens Manufacture and Factory

Fused Silica Laser Window (WFS Series) Broadband 343-355nm UV & 1030-1090nm IR Optical Lens

Our WBK Series (BK7) and WFS Series (Fused Silica) laser windows are precision optical components designed for high-power laser systems. Manufactured with strict tolerances (Diameter Tolerance: +0/-0.13mm, Surface Quality: 40-20 S-D), these windows provide excellent transmission and durability for 1064nm Nd:YAG, 532nm green, and 355nm UV laser applications. Available in a wide range of diameters from 12.7mm to 150mm, they serve as ideal protective windows, output couplers, or beam delivery optics.

WBK Series (BK7) and WFS Series (Fused Silica) laser windows

✅ Precision Manufacturing Standards: All windows feature 40-20 S-D surface quality, λ/4 flatness @ 632.8nm, <3 arc min parallelism, and >90% clear aperture. These standards ensure low wavefront distortion and minimal beam scattering.
✅ Material Flexibility: Choose between BK7 Grade A for cost-effective NIR/visible applications (1064nm, 532nm) or Fused Silica for superior UV transmission (343-355nm) and higher thermal stability.
✅ Wide Size & Thickness Range: From 12.7mm to 150mm diameter, with thicknesses from 1.1mm to 9.5mm. This extensive selection ensures you can find the exact fit for your optical mount or laser head.
✅ High Transmission & Damage Threshold: Excellent transmission (>99.5% with AR coating) combined with high damage threshold makes these windows suitable for continuous wave and pulsed laser systems in demanding industrial environments.
