Typical designs absorb and reflect the unwanted energy but ECI offers special low reflection attenuation films that have very low first and/or second surface reflection. Transmission values can be tailored to your system requirements. These thin film designs are suitable for deposition onto molded polymer optics, glass/metal TO can assemblies, fiber ends and glass fabricated to your requirements. These coatings are commonly used on components in front of lasers or detectors to reduce energy levels to safe or acceptable levels while minimizing back reflection. These coatings can be designed for most any transmission value and typically have back reflection greater than 20 decibels. Custom designs are available if a specific amount of back-reflection is desired.
All coatings are optimized for angle of incidence, wavelength region, incident medium and front or back surface use.
