Dual-Band Infrared Anti-Reflection Coating
Description
Current and next-generation infrared (IR) imaging systems require simultaneous performance at the MWIR (mid-wave, typically 3-5μm) and LWIR (long-wave, typically 8-12μm or 7.5-13.5μm) spectral bands. Dual-band atmospheric transmission performance is challenged to equal or outperform the classic single wavelength band designs. As IR imaging instruments utilize many transmissive elements in the optical path, maximizing per-element throughput is critical to achieve high-levels of system performance.
Reynard’s Dual-Band IR anti-reflection (AR) coatings achieve measured peak transmission values of over 99.5% in both bands.
Depending on specific system requirements, high-performance dual-band AR coatings can be applied to a variety of IR materials, in large or small sizes, and on plano or curved surfaces.
Our coatings are deposited using hard materials in a proprietary deposition process verified to result in excellent environmental durability and spectral performance.
Reynard can customize any filter to meet the performance needs of your system. All manufacturing is done in-house for improved quality, ease of communication and innovative customization.
