8:00AM – 12:00N (PDT USA) – Part 1
1:30PM – 5:30PM (PDT USA) – Part 2
This is a fast-paced, comprehensive optics course for precision engineers, with an emphasis on the principles and applications of non-contact instruments for dimensional metrology.
Part 1 begins with basic geometrical optics of lenses and mirrors, moving up to common optical tools such as telescopes, autocollimators, fringe projection systems, alignment scopes, conventional and confocal microscopes, machine vision, and systems based on focus and triangulation.
Part 2 tackles dimensional metrology applications that make use of the wave nature of light, including diffraction, interference, and holography. This provides the foundation for distance-measuring interferometers and optical encoders, laser Fizeau interferometers for optical surfaces such as lenses and mirrors, and interference microscopes for surface structure analysis.
Hot topics include the latest performance enhancements, new instrument designs, vibration robustness, accommodation of highly sloped, freeform and additively manufactured surfaces, and metrology for smartphone cameras and extended reality systems.
By the end of the course, you will have greater confidence in the selection, invention, and evaluation of optical metrology solutions for practical applications in precision engineering and manufacturing.
This is a beginning to intermediate level course, with material ranging from basic to complex, to provide both an overview and reference for further study. The intended audience is engineers, scientists and measurement specialists interested in gaining a greater understanding of the operating principles and best practice use of advanced optical instrumentation.
