AR Anti-reflection optical window
AR (Anti-Reflective) coated optical windows are precision-engineered components that maximize light transmission by minimizing surface reflections across specific wavelength ranges. Manufactured with premium substrate materials and advanced multi-layer coatings, these windows achieve >99% transmission efficiency, making them essential for laser systems, scientific instruments, medical devices, and aerospace applications where optical clarity is critical.

FAQ
Q: How do I clean and maintain AR coated windows?
A: Use isopropyl alcohol or acetone with lint-free optical wipes. Blow off loose particles first with compressed air. Avoid abrasive materials that could scratch the coating. Store in a dry, dust-free environment.
Q: Do you provide coating specifications and test reports?
A: Yes, every order includes transmission curve data, coating uniformity reports, and quality inspection certificates. Custom testing (LIDT, environmental durability) available upon request.
Q: What is the difference between AR coating and uncoated windows?
A: AR coated windows reduce surface reflection from ~4% per surface (uncoated) to <0.5%, increasing total transmission from 92% to >99%. This dramatically improves image brightness, reduces ghost images, and prevents energy loss in laser systems.
Q: How do I choose the right AR coating wavelength range?
A: Select based on your light source wavelength. Common options include:
- VIS coating: 400-700nm (general imaging, visible lasers)
- NIR coating: 700-1100nm (laser diodes, fiber optics)
- SWIR coating: 1050-1700nm (telecom, night vision)
- Custom ranges available for specific laser lines (532nm, 1064nm, etc.)
Q: Can AR coated windows be used in high-power laser applications?
A: Yes, our laser-grade AR coatings are designed for high LIDT (Laser Induced Damage Threshold) >15 J/cm² @1064nm, 10ns pulse. We offer enhanced coatings for ultra-high-power applications up to 50 J/cm².
