Question I have created a large elliptical reflector with focal length 1 = 100,000 mm, focal length 2 = 10,000 mm, and z position = 55,000 mm. The reflector has approximately 200 surfaces. When I perform a ray-trace, the Audit gives a Defective Object warning message, but the ray-trace appears to...
Question I have set up a Grid Raytrace with a rectangular grid boundary, with half-height x and y set = 10. I also selected a Rectangular Grid Pattern with 10 x-points and 10 y-points. I expected to get a 20x20 beam, but the Irradiance Map shows the beam to be 18x18. What is wrong? Synopsis Grid...
Synopsis Surface and Material Properties - guidelines for when to use one or both Solution "The answer to whether or not you need both a Material and a Surface Property is ""sometimes"". There are some effects that occur at an interface that is best modeled as a Surface Property:
Question I have a zoom system where I want a certain surface parameter to be zoomed in all configurations. However, in some configurations, I want the variables to be tied together (equivalent to each other), and in others I want them to vary independently. How do I do this? Synopsis Tying...

Question I have a lens system that will be altered when subjected to the environment where it will be used. This environment will cause thermal and mechanical stress resulting in lens surfaces deforming to asymmetric surface shapes and glass materials changing refractive index as a function of...
Question I am working on an optical model where I want the system to be telecentric in both object and image space. How do I do this? Synopsis Controlling a lens system to be telecentric Solution When a system is telecentric in both object and image space, it is called "doubly telecentric". OSLO...
