What's Wrong with My Image?

An introduction to specifying and testing Optical Imaging Systems.

We've all had moments when a lens and camera do not produce the results we expected. Sometimes the lens design is adequate, but the lens was not built properly. Sometimes the prototype lens performs well, but the production lenses do not. Sometimes the lens is great, but it's just the wrong lens for the job. Producing a satisfactory imaging system requires starting with the right specifications, and then making sure your lens meets those specifications. This presentation will provide a brief introduction to specifying a lens for your optical system, and a discussion of how to test assembled optical imaging systems to evaluate performance. 

This presentation explores different methods of system metrology, including subjective tests such as visual star tests and resolution testing (1951 USAF), as well as objective methods such as interferometry and bench/MTF testing. The presentation will conclude with a discussion of how to diagnose and resolve optical problems – from manufacturing errors to specification errors.

Who Should Attend:
  • System designers that want to know whether a lens will satisfy their system needs , or learn how to properly select a lens.
  • Lens designers, manufacturers, QC departments that want to test their designs, assemblies, and/or manufacturing process.
  • Professionals and students looking for an overview of optical metrology techniques.

This is a beginner level webinar, and is suitable for individuals with a basic understanding of optical design or metrology. Some intermediate level topics will be discussed, such as testing specific optical aberrations.

Seminar Objectives
  • How to determine what is “wrong” when a lens doesn’t work, and what you can do about it
  • What test equipment is best suited to testing a particular specification or lens characteristic
  • How to test a lens to check that performance correlates with specifications
