Question "I have a license for OSLO that allows multiple installations with one user at a time using the hardware key. I have just installed it on a new machine, and received the following error message: "Your Access Number does not match your ID number" Synopsis Troubleshooting the hardware key ...
Question I am having trouble defining the value of array elements when I dimension an array in CCL. What is the syntax for doing this? Synopsis Defining the value of array elements when dimensioning array Symptoms Perhaps the best way to approach this problem is by way of example: Let's assume that...
Question "What are "vignetting factors" and how are they used?"
Question I want to analyze my lens at different temperatures. I understand that one of the ways to do this is to define the lens as having more than one configuration and change the temperature in different configurations. But in the multi-configuration editor, the cell under "Item" does not accept...
Question Is it possible to use OSLO for designing interferometers? Synopsis Using OSLO for interferometry Solution In an interferometer, the user designs two different optical paths or "arms" of the system. This is easily done by creating two configurations using skip surfaces in OSLO. The current...
Question There appears to be an error in the focal length formula for the Landscape Lens Exercise in the OSLO 6.1 Optics Reference. Is this the case? Synopsis Focal length formula mistake (Landscape Lens Exercise) in Optics Reference Symptoms The first sentence at the top of page 33 (42) in the...
Question I have just installed OSLO and I cannot seem to make the Insert Catalog Lens dialog appear. When I right click on a surface number in the Surface Data Spreadsheet and choose Insert Catalog Lens from the resulting pop-up menu, nothing happens. Is this a known problem? How do I fix this? ...
Question I would like to control the range of my slider wheel in my CCL program code. I also want to set the number of slider increments, so I am trying to use the "realfix" option in the graphwin_sliderassign(gsa) command. But I found that OSLO chooses a different value for the maximum range...
Question I have a lens system that contains tilts and decenters. However, when I print out the paraxial setup (PXC) for the lens, or trace paraxial rays (PXT) I get answers that seem incorrect. For example, the Effective Focal Length (EFL) listed when I choose PXC appears incorrect. What is the...
Question I notice that when I edit my wavelengths in OSLO, the V-number of my glasses seems to change. I thought that the V-number of a glass was calculated based on certain set wavelengths and was independent of the wavelengths you model the glass for. How does OSLO define glass dispersion and v...
