Anti-Reflection Coatings for Plastics, Fibers, Crystals and Semiconductor Materials

ECI is an industry leader depositing optical coatings to temperature sensitive substrates. ECI offers an extensive range of Anti-Reflection (AR) coatings designed to reduce first surface reflection losses, cut return loss on fibers and boost the transmission through your optical surface. Designs are available for deposition onto plastics, molded polymer optics, fiber optic products, crystals and semiconductor materials and other temperature sensitive materials in the 240-2400nm wavelength region. Typical process temperatures below 50°C.

Choose from a typical design below or ECI will design a custom anti-reflection (AR) coating for your application.  Specify your particular wavelength range, angle of incidence, substrate index of refraction, incident medium and polarization requirements to ensure maximum performance for your system. If you are not sure how to specify your coating, our design team will work with you to identify the optimum coating design.

Anti-reflection coatings meet the reflection and environmental requirements of MIL-C-48497*.

Designs comply with military and telecommunication industry standards.  

ECI's durable films on plastic and polymer molded optics are resistant to organic solvents and are an excellent choice for a wide variety of products.

*In some cases, composition of substrate material affects coatings environmental characteristics.
