Solid-state Laser Crystal and Device Laboratory Yen-Yin Li NTU 3 Introduction Basic ray tracing practical only for paraxial analysis Aberrations are time consuming to calculate Diffraction also tough Computer Aided Design (CAD) Use commercial tools to do all of the number crunching Popular software packages – ZEMAX, OSLO CAD tools do not automatically design the lenses, they only help characterize and optimize your designs.

Solid-state Laser Crystal and Device Laboratory Yen-Yin Li NTU 12 Summary What does ZEMAX do? ZEMAX is a program which can model, analyze, and assist in the design of optical systems. The interface to ZEMAX has been designed to be simple to use, and with a little practice it can allow very rapid interactive design. What doesn't ZEMAX do? Neither the ZEMAX program nor the ZEMAX documentation will teach you how to design lenses or optical systems. Although the program will do many things to assist you in designing and analyzing optical systems, you are still the designer. The ZEMAX documentation is not a tutorial on optical design, Technical support available to ZEMAX users includes assistance in using the program, but does not include tutoring on fundamental optical design principles. If you have little or no experience in optical design, you may want to read up on any of the many good books available on the subject.
