Question "I am attempting to acquaint myself with the Gaussian Beam propagation options in OSLO (ABCD Analysis, Astigmatic Gaussian Beam and Fiber Coupling). I have read and followed the "Gaussian Beam and Fiber Coupling" tutorial offered on your website. The problem is that when I change the...
Question I am currently trying OSLO for Linux, but I am experiencing some user interface problems (window control, graphics not being updated, crashing, ...etc.). Are you targeting a specific Linux distribution that will work better than others? Synopsis Problems with OSLO Linux Solution ...
Question I am currently reading the OSLO Optics Reference 6.1 manual. On page 11 of the hardcopy version (page 20 of the electronic version), I am asked to open the "Landscape 1.len" file. I don_t seem to have this file. Where do I find it? Synopsis Locating the Landscape Lens file Solution ...
Question Can OSLO handle non-isotropic media, such as Quartz? Synopsis Non-isotropic media and OSLO Solution OSLO has the capability of tracing rays through uniaxial birefringent materials such as calcite (PremiumEdition only). In the physical world, a ray incident upon a birefringent material will...
Question How do I change the way a command works in OSLO? I have located the command I want to change and it is in a CCL file in the public CCL directory. Can just go ahead and edit the file? Synopsis Editing of public CCL files Solution OSLO allows users the complete flexibility of changing or...
Question I am trying to convert an output *.hpg file (Hewlett Packard graphics file) into a postscript file. I used to be able to successfully do this using the hp2ps command. Since then there has been a lot of change in the people that control the Unix machines here and the program was lost. They...
Question Is it possible to calculate light emission angles, propagation angles, and paths through multilayer coatings? Synopsis Calculation of ray angles through multilayers? Solution Propagation angles are calculated throughout the optical design and are preserved through multilayer coatings....
Question I am having trouble using the fopen() command to write a new file to a specific directory. I can't seem to find the file after I create it. Do you have some advice or examples I can follow? Synopsis Specifying a directory when using fopen() Solution NOTE: There are examples in this note...
Question I have a situation where my lens has a 2nd order aspheric term on an optical surface. The paraxial PU curvature solves and the paraxial EFL that OSLO calculates (by default) does not include this aspheric term. How can I target a real-ray based EFL for my lens in optimization so that 2nd...
Question 1) About variables insertion, before optimizing: how can you define the distance between image and object and say for instance that it should be 27mm? 2) Variables: how can you insert distortion among certain values? 3) Where are indications about "relative illumination" of a system to be...
