Our in-house design team will work closely with you to design a custom dielectric mirror coating that meets your performance objectives. Typical designs provide greater than 99.5% reflection over your specified wavelength region.

ECI manufactures highly reflective low loss dielectric mirror coatings for glass optical materials, including:

  • Fused Silica
  • Precision Glass Optics
  • Molded Glass Elements
  • BK-7
  • High Expansion Glass
  • Gradient Index Glass
  • Ultra Thin Wafers
  • Low Index Glass

Contact our design team to discuss your specific requirements including: substrate material, percent reflectance, angle of incidence, polarization state and incident medium. Typical designs are suitable for applications from 248nm – 2500nm.

ECI’s Dielectric Mirror Coatings meet the durability and environmental requirements of MIL-C-48497; Dielectric Mirror Coatings on glass and other substrates that withstand elevated temperatures meet the environmental and durability requirements of MIL-F-48616.

Samples and theoretical design curves available upon request!

ECI will also deposit your proprietary thin film mirror design.

Typical Dielectric Mirror coatings for glass and metal substrates:
coating performance is optimized for 0° A.O.I. and air boundary unless otherwise noted


High Laser Damage Threshold Highly Reflective

Wavelength LDT* Pulse width
355 nm 2 J/cm2 20 ns
532 nm 6 J/cm2 20 ns
1030 nm 0.47 J/cm2 319 fs
1064 nm 40 J/cm2 20 ns

*Typical values verified through independent test laboratories. Actual LDT performance is dependent on substrate selection, surface preparation, and system design.
