Optical coatings are a fundamental part of most optical systems, but in many instances, the various properties of optical coatings remain poorly understood by those specifying and using them.  The type of performance that can be anticipated with an optical coating, how the deposition process influences the ultimate performance, and how coatings should be evaluated are all critical questions (among others) that do not always have easy answers.  Regardless, an improved understanding of how to design a coating for a given application as well as process-specific influences on the component performance can significantly aid in the successful integration of coatings into an overall system design. 

Fundamental principles of optical coating design

  • Key aspects to successfully specifying an optical coating
  • Optical interference basics (constructive/destructive interference)
  • Optical coating materials (dispersion, refractive indices, material selection)
  • Fundamentals of anti-reflective coatings
  • High-reflective coatings
    • Dielectric
    • Metallic
  • Polarizer coatings
    • Narrowband
    • Broadband
  • Limitations on optical coating design (other wavelengths, error analysis)

Deposition and characterization of optical coatings

  • Types of deposition processes
    • Evaporation
    • Ion-beam sputtering
    • Magnetron sputtering
  • Substrate fixturing
  • Thin-film uniformity (substrate size, shape, system design)
  • Mechanical stresses
  • Other coating properties (hardness, abrasion resistance, humidity, salt fog, laser damage)
  • Spectral and photometric evaluation of coated substrates (one side vs. total component, substrate material, angle of incidence, f#, specular vs. diffuse)
  • Wavefront measurements of coated partsInstructor:
