Perfmag2 is an example of a perfect lens. It should be studied to understand the difference between a perfect lens and a paraxial lens, as well as the definitions of aperture-based operating conditions used in OSLO. A perfect lens is one that forms a sharp undistorted image of an extended object on...
Question I have a system with a mirror at 45 deg tilt. I invoked the tilt and bend option on the tilted mirror in order to set the remaining surfaces at the correct 90 deg orientation. However, now I want to see the effect of tilting (or decentering ) the mirror alone with respect to the other...
Question What's the difference between SCL and CCL? Synopsis SCL versus CCL Solution SCL is a subset of CCL than uses predefined variables and is compiled "on-the-fly", so it is slower and less comprehensive than CCL. However, for simple tasks that require only a few lines of code, SCL may be...
Question When I click on the autofocus button, I get a different value each time I press it. Why does it do this? Isn't there a best focus position? Synopsis Autofocus consistency Solution "When you click on the autofocus button, a mini-optimization takes place. A first derivative of the spot size...
Question I am using automatic importance sampling and for some surfaces, the Prescription is being set to -1. Why does this happen?
Question When I'm optimizing or performing an analysis on a lens, I sometimes get an error message that indicates: Warning: reference ray trace failed. What is the problem? How do I correct it?" Synopsis What is a reference raytrace failure and how to correct it Symptoms In versions of OSLO prior...
Question "I am using a Gradium gradient index material (from Lightpath Technologies) in my system. When I use it in a regular way, it works fine. However, when I " invert" it so that I can insert a mirror before it, it doesn't appear to work properly. What is wrong? NOTE: "Invert" is a command in...
