Introduction to Lens Design and Optical Engineering
May 14 - May 15
Title: Introduction to Lens Design and Optical Engineering
Thu, May 15: 1-3 pm,GB220 (Practical)
Description (Theory): This workshop will give an introduction to lens design, with emphasis on the non-idealities of actual lenses, as well as a discussion of optical system layout and lens fabrication. This includes a discussion of all the primary aberrations of lenses, both axial and off-axis along with various methods to compensate or minimize the effects of these aberrations. Field lenses and erector lenses will be introduced, as well as field stops, aperture stops and baffles. Attendees will also learn how to use commercially available lenses, and some of the pitfalls one should avoid when using these lenses.
Description (Practical): This demonstration shows the use of Ansys Zemax (Student Edition). Some lenses will be analyzed, to demonstrate the power of raytracing software to understand lens aberrations, as well as automatic lens optimization to minimize a merit function. The aberrations introduced by focusing through a window, as well as aberrations due to imperfect placement and alignment will be demonstrated. This includes off-axis beams, as well as conjugate distances that are different from those that the lens was designed for. Because most users do not have the ability to manufacture custom lenses, the workshop will also show and example of combining stock lenses instead of one custom-made lens.
Bio: Emanuel Istrate received his Ph.D. in Photonics from the University of Toronto in 2005. As the Academic Program Coordinator of the Institute for Optical Sciences at UofT, he set up a number of courses and training programs in optics at all levels of the University. Part of his current teaching includes a course in the Vic One Arthur Schawlow program in the Physical Sciences, which looks at communications and social interactions of scientists. He also teaches a course covering both the art and the science of holography, as well as a course on creativity in the sciences. He has made contributions to lensless microscopy methods, entrepreneurship training programs and to collaborative projects with industry.
