Thin film designs are deposited with Ion Beam Sputtering (IBS), Leybold APS or Ion-Assisted E-beam (IAD) deposition systems to ensure that the coatings meet your required optical performance, laser damage threshold and environmental stability.

Clean room facilities ensure compliance with your most demanding surface quality requirements. High performance optical filter coatings are deposited on wafers, custom optics, polymers, fibers, crystals, semiconductors, garnet and glass substrates up to 200mm in diameter.

ECI’s design team is always available to work with you to identify the optimum design for your system. Sample designs can be generated to illustrate the theoretical coating performance for your particular angle of incidence, substrate, incident medium and wavelength region.

ECI uses Flow Cytometry for a wide variety of applications including:

  • Laser Safety
  • Sensing applications
  • Detector trimming
  • Biomedical laser systems
  • Aerospace
  • Telecommunications

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.
