Course Description

When doing professional optical tolerancing it is important to try to reproduce what may happen in fabrication and mounting. This can easily be done using CODE V’s tolerancing tools. However, we need to understand what happens during fabrication. We need also to understand how we can specify the tolerances using ISO 10110. 

In this workshop we will learn about all the features in CODE V that help us to find the right tolerances and how we can predict the yield in fabrication.

We will apply what we learn in realistic examples using CODE V. This workshop is open to discuss the problems that come from your experience.  

This workshop is intended for those users who are already familiar with CODE V.

Speakers

About the instructor: Rainer Jetter has over 35 years of experience in practical optical imaging design. After studying physics and astronomy at the Ruprecht-Karls University in Heidelberg, he joined AGFA-GEVAERT AG in Munich to become a classical lens designer and, subsequently, the head of the optical design group there. It was even then that his main fields of interest included fabrication tolerances in optical design. Together with Dr. Geoff Adams, one of the authors of the Kidger tolerancing program, he examined its applicability by comparing predictions made under that program to results turned in at AGFA’s optical shop. Thereafter, he worked part-time as a freelance optical designer for various companies such as Zeiss Oberkochen, as well as part-time as an employee at Rodenstock Präszisionoptik and Schneider-Kreuznach. During his professional life, he has designed more than 100 optical systems that have made their way to success. Part of that success was based on his reasoned view that fabrication tolerancing is a crucial stage of the optical design process. For more than ten years now, Rainer Jetter has taught special courses on tolerancing in lens design at optical companies and at the University of Applied Sciences in Munich.
