AT Optical Instruments Co., Ltd.

8.0 µm ≤ λ ≤ 12.0 µm

Broadband AR Coatings engineered for the LWIR spectrum, our BBAR coatings deliver ultra-low reflectance across 8–12 μm, enhancing system efficiency, image clarity, and measurement precision—even in the most demanding environments.

Narrowband AR Coatings optimized for CO₂laser applications, our narrowband anti-reflection (NBAR) coatings deliver reflectance below 0.25% at 10.6 μm, maximizing transmission and enhancing signal-to-noise performance. Designed for single-wavelength operation, they preserve beam polarization and power stability, ensuring reliable performance in high-precision infrared and laser systems.

8.0 µm ≤ λ ≤ 12.0 µm

Combining anti-reflection performance with the exceptional hardness of diamond-like carbon, our AR + DLC coatings deliver high transmission, reduced surface reflections, and superior resistance to abrasion, humidity, and contamination.Ideal for demanding infrared and optical applications, they ensure long-term stability and reliable performance in the most challenging conditions.
