AS OF 2016 GCL HAS EXPANDED TO INCLUDE:
  • Coatings on fiber optics
  • Coatings on plastic substrates, adding to GCL's line of thin films on glass and metal
  • A new high capacity vacuum chamber bringing the number of systems to eight

Deposition Techniques and Coatings

From research and development to high volume runs, GCL's expertise covers custom design, custom tooling, evaluation and testing to final production.

Using the following techniques:

  • Resistance Source Thermal Deposition
  • Resistance Source Thermal Deposition
  • Electron Beam
  • Ion Assisted Electron Beam
  • Ion Beam Sputtering

(Note: Ion Beam Sputtering provides the advantage of the highest packing densities, giving the thin-film coating exceptional adhesion, abrasion, resistance and ruggedness).

Applications include coatings such as:

  • Broadband Anti-reflection
  • V-Coats
  • Super V-Coats
  • MgF2
  • Dielectric High Reflectors
  • Protected Aluminum
  • Enhanced Aluminum
  • Protected Silver
  • Protected Gold
  • Beam Splitters
  • Neutral Density
  • Dichroic
