Understanding Diffraction, Modulation Transfer Function and Image Simulation in Zemax OpticStudio Software

This course offers a review of diffraction theory and the different domains of validity of Ansys Zemax OpticStudio analyses. It also includes an example of how to design a Double Gauss for specific MTF targets, and how to use Image Simulation to visualize pictures as imaged through the modelled system.

Learning Outcomes:

Following completion of this course, you will be able to:

• Understand diffraction theory.
• Comprehend PSF, MTF and Strehl ratio.
• Design a Double Gauss.
• Optimize with MTF targets.
• Use ray aiming.
• Run the image simulation analysis.

Prerequisites:

Completion of the following course is highly recommended:

• Introduction to Ansys Zemax OpticStudio Software
• Reviewing Optical Design Principles with Ansys Zemax OpticStudio Software

Please note: These training materials were developed and tested in the 2025R1 release.
