CIE Plots

Question In Analysis/Irradiance Options/Map Data/Quantities to plot, there are a lot of map types to select. Could you provide some information about "CIE(xy)" and "CIE(u'v')" or their applications in optics?

ccl examples moved from Knowledge Base to OSLO Examples page on website

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?

GRIN Lens: GRINLENS.LEN - A Gradient Lens for CD Pickup

The GRIN lens (gradient-index lens) demonstrates the use of gradient-index materials to create a focusing element, particularly for a CD player. In this design, the gradient coefficients serve as variables, but an alternate approach involves fixing the gradient and varying the curvatures of the...

29. OSLO Tip: Error function

OSLO analysis causes OpenGL error message

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?

Program crashes when some analyses are performed on non-sequential systems

Question OSLO crashes when certain analyses are performed on a system containing a non-sequential surface (NSS) group. What is wrong?

Define Diffuses: Creating Properties for Rough Finish That Diffuses Light

Question I would like to model a plastic object with a rough finish that diffuses light. How can I create the properties for this in TracePro?

Managing different editing modules

Question When I look through the ASCII text of a lens prescription file, I notice that the commands are in different groups. How many different groups are there? Do I have do worry about these groups when I am creating different macros?

Problems with image analysis routines.

Question Why don't the image analysis routines work with my system? Synopsis Problems with image analysis routines. Solution By far the biggest problem encountered in this area is the failure to use adequate pupil sampling to characterize the image. To compute a spot diagram, point spread function,...

Number of pixels in Irradiance Maps, Plot Points in Candela Distribution Plots, and Smoothing

Question When viewing an Irradiance Map or a Candela Plot, I find that changing the settings for Number of Pixels, Plot Points, or Smoothing causes the results to vary significantly. How do I know what are the proper settings, and how do I know if I have traced enough rays?
