Question Why do I see "Warning Message - out of valid wavelength range (400 to 700)", and how can I resolve the problem? Synopsis Warning Message - out of valid wavelength range (400 to 700) Solution TracePro 7.2.0 introduced a new feature in TracePro. If you select any Material Property in the...
Question If a source which has a specific spectral profile is used for raytracing, how is the power, in FC or in lumen whichever, in each wavelength calculated? I'd like to know the relation between the weighting of each wavelength in RaytraceOption/Wavelength and the set flux power on...
Question I am using automatic importance sampling and for some surfaces, the Prescription is being set to -1. Why does this happen?
Question How do I rotate a block in Scheme? Synopsis Rotating objects with TracePro macros. Solution The (edit:rotate) command is used to rotate a given object or list of objects. The simple example below creates a cone and rotates the cone by 45 degrees. ; Create a cone centered at the origin...
Question I have found that the value of Max Candelas reported at the bottom of the Polar Iso-Candela Plot and the Rectangular CandelaDistribution are different. However, when smoothing is ON, the values are much closer. Why is there such a variation in the Max Candela value that is reported?
Question Candela Plots - changes to reported values - Min, Max, Collected Flux, Total Flux, Total Rays, Efficiency
Question When I launch TracePro, the program crashes (I observe a Runtime Error message). How do I get TracePro running again? Synopsis TracePro crash at Startup Solution "The possible causes of the problem differ if TracePro has run successfully on this PC for a period of time and then it...
Question I understand that you have attempted to use NetMeeting with TracePro, but only the frame of the TracePro Window appears without any detail in the model window. Synopsis Graphics problems when trying to view TracePro with NetMeeting Solution This is a graphics issue, related to where the...
Question When I attended the recent TracePro training course, there was mention of references that related surfaces cleanliness levels (specified by MIL-STD-1246C) to cleanroom classifications (specified by FED-209D).What I am looking for is research that was published on how to link MIL-STD-1246...
Question As an inexperienced optical designer, I have little idea what degree of smoothing (i.e. what range of waist radii) is generally appropriate to provide the most realistic answers. I'm sure there's no one right answer, but are there any rules of thumb one can use to determine an appropriate...
