Designed for high-performance optical and sensor systems, our Custom Infrared (IR) Anti-Reflection (AR) coated glass significantly minimizes surface reflection and maximizes IR light transmission. Utilizing advanced vacuum deposition technology, we apply precise dielectric thin films tailored to your specific infrared wavelength requirements (NIR, SWIR, MWIR, or LWIR). Combined with our rigorous darkroom inspection protocols, these IR windows guarantee zero-distortion signal transmission, making them the critical choice for LiDAR, thermal imaging, and advanced sensor applications.
Key Features & Technical Capabilities
- Maximum IR Transmittance: Custom-engineered single-layer or multi-layer broadband AR coatings to achieve exceptional transmittance (T > 96% to 99%+) at your target wavelengths, such as 850nm, 905nm, 940nm, or broader infrared bands.
- Minimized Surface Ghosting: Effectively reduces optical noise, ghost images, and light scattering, ensuring maximum signal-to-noise ratio (SNR) for precise sensor detection.
- Exceptional Durability: Our AR coatings feature excellent adhesion and environmental stability, passing strict military and industry standards for abrasion (e.g., cheesecloth/eraser test), temperature cycling, and humidity resistance.
- Versatile Substrates & CNC Shaping: Available on a variety of substrates including Borosilicate, Fused Silica, Sapphire, and specific IR materials. We offer precise CNC shaping, stepping, and custom black masking (IR-blocking ink) to fit your optomechanical assemblies perfectly.
- Strict Optical Defect Control: Every IR window undergoes 100% focused-light inspection in our cleanroom to meet strict Scratch/Dig standards (e.g., 40/20, 20/10), ensuring no microscopic flaws interfere with the infrared beam.
