Common examples of MacLeod coatings

This article shows common, thin-film components manufactured by MacLeod. As the manufacturer indicates, the components should not be considered the best that can be produced. For these coatings, the incident medium is air unless otherwise noted.
These MacLeod coatings are available in the standard COATING.DAT file that’s included in the OpticStudio installation files.

How to Add Coating and Scattering Functions to Non-Sequential Objects

Non-sequential objects are 3D volumes. Thin-film coatings, and scattering functions, are surface properties of these 3D volumes. This article explains:
  • The concept of the "face number" of an object
  • How thin-film coatings and scattering functions are applied to the various faces of an object
  • Special issues involved in applying these properties to CAD objects
