UV, VIS, NIR Anti-Reflective: Dual Band Coatings

These Dual Band Anti-Reflective Coatings are ingeniously designed to provide low reflectivity and scatter losses across the visible spectrum (430nm to 700nm), as well as at 1.06µm, a wavelength typically employed in laser applications such as range-finding equipment.

The Dual Band Anti-Reflective Coatings are engineered for the demanding requirements of military applications. With an average reflection from 420nm to 700nm of less than 0.6%, these coatings facilitate excellent visibility in the operational field. Additionally, the maximum absolute reflection from 420nm to 680nm is less than 1%, and at 1.06µm, it is less than 0.3%. This guarantees precise and accurate laser measurements, contributing significantly to mission success.

Built to endure, these coatings comply with multiple military environmental specifications. They meet the stringent conditions of MIL-M-13508C para 4.4.6., MIL-C-675A, MIL-C-675A para 4.6.8., and MIL-C-14806A, making them robust and reliable even under the toughest of conditions. These criteria ensure that our Dual Band Anti-Reflective Coatings can withstand rigorous usage without compromising on performance.
