Customized Square Sapphire Optical Window with Through Hole
Product overview
Our square sapphire optical windows with through holes are precision-engineered from high-quality synthetic sapphire (Al₂O₃), one of the hardest optical materials available. These windows provide excellent mechanical strength, thermal stability, chemical resistance, and wide spectral transmission from UV to NIR. Designed for applications requiring both optical clarity and mechanical durability, they protect sensitive components while allowing light or laser transmission.
Featuring a through hole, these windows are ideal for mechanical integration, alignment, vacuum feedthroughs, fluid or gas channels, and other specialized applications.

FAQ
Q1: What materials are used in your sapphire windows?
A: We use high-purity synthetic sapphire (Al₂O₃), one of the hardest and most chemically resistant optical materials, offering excellent thermal stability and wide-spectrum optical transmission.
Q2: Can the windows be customized?
A: Yes. We offer customization for size, thickness, shape (square, round, rectangular), hole diameter and location, surface flatness, and crystal orientation according to your requirements.
Q3: How precise are the holes and surface quality?
A: Holes are precision-drilled with chamfered edges to minimize stress. Surface quality is high, with scratch/dig options of 80/50, 60/40, or 40/20 and flatness typically 2λ, ensuring optical clarity and durability.
