Course Introduction:
This is our well-known standard course on the whole field of optical coatings with an emphasis on hands-on computer-aided design. The course is a mixture of formal lectures and hands-on tutorials with a computer for each student. It is important not only to know how to use the computer, but also to understand the computed results, and both are covered in detail. Calculation of the optical properties of a given thin-film coating is straightforward. Designing for desired optical properties is rather more difficult. Reverse engineering that attempts to identify the errors responsible for manufacturing failures is similar to design but requires an even greater level of understanding. Computers are absolutely necessary in these tasks and much of the course will involve learning effectively to use powerful computer tools, but knowledge of deposition techniques and thin-film behavior is also necessary for the effective designer. Extensive notes have been specially pre-pared for the course. They represent a valuable reference source and can not be obtained except by taking the course.


Christopher Andrew Clark
Christopher Andrew Clark is Director of Research at Thin Film Center.
He graduated from the University of Sussex with a degree in Electronic

Engineering and is a Chartered Engineer. After a Lectureship at Brighton Technical College, he had a distinguished career in computer and software development for a variety of systems from radar detection to optical inspection,
before joining Thin Film Center in 1993. His responsibilities include the development of the Essential Macleod software. He has more than twenty publications on the subject of optical coatings.
