XMT Plots transmission as a function of field (CCL)
Question This record is outdated. It has been superceded by record #445 XMT Plots the fall in transmission as a function of relative object height arising from vignetting. It illustrates how a custom error handler prevents reference ray failures terminating execution of a CCL command. Synopsis XMT...
Information about data exchange formats for OSLO
Question I am interested in exchanging data between OSLO and other programs. How do I accomplish this? Synopsis Information about data exchange formats for OSLO Symptoms There are two main ways to exchange data between OSLO and other programs:
Defective Object Warning Message
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...

Grid Raytrace - calculation of actual Beam Width
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...

Surface and Material Properties - guidelines for when to use one or both
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:
Tying variables together in a multi-configuration (zoom) system
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...
