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...

Simulating a binary DOE lens diffractive optical element
Question How do you simulate a binary diffractive optical element (DOE) in OSLO? Synopsis Simulating a binary DOE lens diffractive optical element Solution Yes. OSLO's CGH surface option calculates the direction of rays from the grating groove spacing. The binary construction order and zone depth...
Model of the human eye
Question I need to model the human eye in OSLO. Do you have an example I can use? Synopsis Model of the human eye Solution Lens models of the human eye can be found in the "...publiclenlibwalker" directory. In an OSLO Standard and Premium installation, this directory has two sub-directories. In...
