Wheel mouse not functioning properly in the Surface Data Spreadsheet
Question I notice that if I use my IntelliPoint wheel mouse to roll up and down on any of the spreadsheets in OSLO, it works in only one direction. After I hit the bottom of the spreadsheet, the mouse wheel works for rolling up only. If I have too many element groups in the surface data...
CCL and pointers.
Question Why doesn't CCL have pointers? Synopsis CCL and pointers. Solution They are not needed. The main reasons for pointers in C concern the structure of arrays, and passing function parameters by reference. CCL uses conventions similar to Fortran for these functions, allowing hidden structs on...

Decentering an optical system with respect to object space illumination
Question I have set up an optical system where the light passes through the center of the optics. When I decenter the optical system (in the +Y direction, for example) the light beam doesn't appear to change - it is not decentered in the -Y direction as I would expect. What is wrong? Synopsis ...

Applying a field weighting function during optimization
Question I notice in the Optimization Conditions dialog box (see the menu item "Optimize>>Optimization Conditions"), that I can apply field, pupil and color weighting functions. How can I do this? Synopsis Applying a field weighting function during optimization Symptoms You can apply a custom field...
Specifying size and location of exit pupil
Question How can I control the size and location of the Exit Pupil in my optical system? Synopsis Specifying the size and location of the exit pupil Solution The Exit Pupil is the paraxial image of the Aperture Stop in image space. The optics between the Aperture Stop and Image Surface perform this...
Exporting FFT data to a file
Question I would like to output the amplitude and phase of the point spread function to a file. The PSF is calculated using an FFT, so basically I would like to output the entire FFT array to a file. How can I do this? Synopsis Exporting FFT data to a file Solution The graphical PSF analysis uses...
