Question OSLO does not seem to show some surfaces in my lens. Why is this? How do I force a surface to be shown when I draw a lens? Synopsis Showing a surface when drawing a lens Solution Try the following: Make sure the Aperture Radius of your surface is large enough to be seen in the scale of...
Question I would like to use custom materials for my lens design. What data do I need from the glass manufacturer in order to model it like the usual glass in the "GLASS" column of the surface data spreadsheet? Synopsis How to add custom or specialized materials (glasses) to a design Solution There...
Question I created two CCL programs ("aprog" and "bprog") and placed them in separate CCL files of the same names ("aprog.ccl" and "bprog.ccl" respectively). I verified that both programs work correctly by themselves. Then I changed "aprog" to call "bprog" from within the code and I got an error...

Question I am attempting to control the derivative increment of some variables during optimization. But whenever I set the derivative increment in the Variables Data Editor, I find that OSLO overrides it during optimization. How can I force OSLO to use my intended values? Synopsis Calculation of...
Question I have created a lens system that includes a Diffractive Surface described by Zernike coefficients. I note that term #32 of the Asymmetric Zernike Phase terms appears too large. Is this term calculated correctly? Synopsis Incorrect calculation of Zernike Phase term #32 Solution The...
