Low-temperature processes minimize out-gassing from epoxies and cladding materials. Our high-energy deposition processes produce extremely dense and environmentally stable films suitable for devices that must pass extended humidity and temperature cycling tests.

ECI has the experience to fixture, clean, coat and inspect Fiber Optic Devices including bare fibers, jacketed fibers, ball lenses, laser bars, window caps and many others. Preparation and coating processes are performed in a clean room environment. In-house tooling is available for coating many common fiber assemblies.

Custom designs are available upon request.

The links below are examples of some of our standard optical coatings for Fiber Optic Devices:

Anti-Reflection Coatings

Low-temperature designs include super low, narrow band laser wavelengths, C-Band, L-Band and dual wavelength coatings.
Typical Anti-Reflection (AR) Designs

Metal Mirror Coatings (Near Infrared to far Infrared)

ECI deposits enhanced Gold Metal Mirrors for many laser diode applications including biomedical devices, scanning, sensing, military and fiberoptic assemblies. In accordance with MIL-M-13508C.

Dielectric Mirror Coatings

ECI’s low-temperature all dielectric mirror coatings designed for direct deposition onto fiberoptic devices including: fibers ends, GRIN rod lenses, laser diodes, laser bars and other temperature sensitive components. In accordance with MIL-C-48497.
Typical Dielectric Mirror Designs

Beamsplitter Coatings (240nm – 2000nm)

Dielectric and Metal Beamsplitters designed to separate incoming light into two components consisting of reflected and transmitted beams. All coatings are optimized to meet customer specific requirements including ratio of reflected versus transmitted light, AOI, wavelength region, polarization and incident medium.
