ECI’s coating designs can be optimized for maximum performance from the 240nm – 2400nm wavelength region. Specify your particular wavelength range, angle of incidence, substrate index of refraction, incident medium and polarization requirements to ensure maximum transmission for your system. Designs include V-coats, broadband, super broadband, dual band and narrow band coatings.

Applications include: miniature optics, display windows, industrial instrumentation, medical optics, port windows, and fiber optic and laser components.

ECI’s anti-reflection coatings meet the reflection and environmental requirements of MIL-C-14806A and MIL-C-48497. Designs comply with military and telecommunication industry standards.

Examples of LDT

High Laser Damage Threshold Highly Reflective & Filter Coatings

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.

Designs are RoHS compliant.
