Question When I exchange OSLO lens files between Unix and Windows platforms (I sometimes run OSLO on Unix, using Windows emulation software), I notice that my optical prescription has many air spaces between the surfaces of my original design. What is going on? How do I stop this? Synopsis Extra...
Question Do you have directions for setting up Fresnel lens in OSLO?
Question I want to vary the aspheric coefficients of a surface during optimization, but I can't seem to choose the aspheric coefficients when I try to assign variables for that surface. What is wrong? Synopsis Assigning aspheric coefficients as variables for optimization Solution "OSLO requires...
Question "What does "vignetting" mean as it applies to optical design?" Synopsis Definition: vignetting Solution "An optical ray is vignetted when it passes through (or would have passed through) the limiting aperture of an optical system (the system Aperture Stop), but instead gets blocked by some...
Question I would like to change the colors of the rays that are drawn in the standard lens drawings. By default, green, blue, red,...etc. is chosen. How do I assign rays specific colors? Synopsis Changing the ray colors in a lens drawing Solution Note that fans of rays in lens drawings are drawn...
Question I want to temporarily turn the graphics scale bar off in some of my graphics drawings. When I set the OSLO preference "graphics_labels" to be "off" using either: set_preference graphics_labels off; or, stp glab off; the graphics scale disappears from the shaded solid drawings, but it...
Question I would like to get paraxial PY and PUY at different surfaces as well as real ray trace values. How do I extract ray data within a CCL or SCP macro command? Please note that OSLO contains two macro-programming languages:
Question I believe there used to be some ccl Examples in the Knowledge Base at one time, but I am not finding them in my current search. Where are they located?
Question When I attempt to perform an analysis in OSLO (e.g. "Source>>View Extended Source Image>>Lambertian"), in the output graphic I get the message: "OpenGL is needed for that plot". What is the problem? How do I correct this situation?
