Summary and References
This article has discussed how to design afocal systems in ZEMAX. The main points are:
- The major difference between focal and afocal systems is that focal systems are measured in spatial units and afocal systems are measured in angular units
- The Afocal Image Space switch switches ZEMAX from using spatial units to angular units where appropriate
- The default merit function tool allows you to easily target both spatial and angular properties of the beam
- The IMSF operand allows you to target spatial properties at one surface, and angular properties at another (for example) to control both focal and afocal properties of the optical system at any surface
- The AFOC multi-configuration operand lets you define focal and afocal configurations of a design.
- The ZPL keywords GETSYSTEMDATA and SETSYSTEMPROPERTY allow control of the Afocal Image Space switch from within a ZPL macro

Helpful. Better to have it in PDF format for hard print and later review.

Hi
You can use the "Print Article" link to get a printer friendly version and then print it to either a real printer or a pdf generator. I'll look into what's involved in providing a pdf generator as part of the Knowledge base however.

Easy to understand and follow. A PDF version for easier printing would be helpful.

It was very helpful!!
Just as many have mentioned I guess it would be very helpful if all the articles come in a pdf format!

Very helpful. I was able to print the whole article from page one -- just click "print article"
I had an error somewhere. My spot diagram came out different.

Great information! There are lots of Zemax users who do nothing but laser system optical design. Could you offer a course, perhaps a three-day short course, that focuses on design of afocal systems?
