⏰Large Rectangular Rounded-Corner Stepped K9 Glass Window

The window features rounded corners on all four edges. This design serves both functional and safety purposes: it effectively eliminates stress concentration points commonly found at sharp 90° corners, thereby substantially reducing the risk of fracture under mechanical load, thermal cycling, or high-pressure/vacuum conditions.

If you are interested in this window, please feel free to contact us at any time. We look forward to hearing from you.

🔥 When Size Matters: Bigger Optics, Bigger Performance 🔥

We are pushing the boundaries of optical manufacturing with our latest large-format reflector!

Featuring an oversized aperture (200mm+ class) crafted from H-K9L optical glass, this component is built for system integrators who need to collect more light, reduce beam divergence, and achieve higher signal-to-noise ratios.

💎 What sets this large reflector apart?
✔️ Substantial Light-Collecting Area: Ideal for beam expansion and high-energy laser paths.
✔️ Premium H-K9L Substrate: Ensures surface flatness and thermal stability across the entire clear aperture.
✔️ High-Performance Coating (Side A):

≥90% reflectance @ 900-950nm (NIR)

≥70% reflectance @ 550-650nm (Visible)
✔️ Seamless Integration: Designed to fit into large-scale optical benches and custom housings.

The ability to produce large-diameter reflective optics with high uniformity is a testament to our advanced manufacturing capabilities. If your project requires oversized components, we are ready to collaborate!
