Question "I am using OSLO-EDU and attempting to follow an example from your documentation (i.e. the OSLO Optics Reference). I can follow everything just fine until I get to optimization. When I follow the directions and attempt to perform an optimization iteration, I get the error message: Error...
Question I am doing a polarization calculation where I an sending either linear or elliptically polarized light into my system. I seem to be getting incorrect answers for some orientations of the polarization axis of the input beam. Is there a known problem related to this? Synopsis Known problem...
Question I am attempting to copy a few of cells from an electronic spreadsheet (such as MS Excel) into OSLO, but OSLO only accepts the entry for the first cell. Is there a trick that I am missing? Synopsis Copying multiple spreadsheet cells into OSLO Solution The cells in OSLO's spreadsheet have...
Question I am trying to run UltraEdit 8.0 on Vista. It prompts me to enter the license info, and I enter it, and then it prompts to exit and restart the program. After the restart, it prompts for the license info again .... what can I do to get it working? Synopsis UltraEdit does not retain license...
Question This record is outdated. It has been superceded by record #445 XMT Plots the fall in transmission as a function of relative object height arising from vignetting.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...
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:
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...
Question Several times I have had the need to measure a distance, say from the front surface of a lens to the aperture stop, or the length of a group of lens elements (for example, surface 5 to surface 11). Is there an easier way of doing this than manually adding up all the thicknesses? What...
