Optical Coatings for Telescopes Presented by Alan Ward - Moonward Vacuum Coatings
Optical surfaces of all modern quality astronomical instruments are coated with very thin layers of metallic or dielectric materials to improve optical performance. This presentation will describe the mechanics of depositing & the theory of thin-film interference, and give an overview of what every telescope user should know about the many available optical coatings for lenses & mirrors and the caring for them.
