Germdiff illustrates the use of a diffractive surface to correct the chromatic aberration of an infrared system, as well as an aspheric to correct spherical aberration. One of the first practical applications of diamond-turned computer-generated holograms was a single element achromat for the...
Question What version of SolidWorks is compatible with TracePro and TracePro Bridge? When I save a TracePro file from SolidWorks SP4.0 (with TracePro Bridge) and attempt to open it in TracePro 3.3.6 I get an error message indicating that the file is from a later version of ACIS. Synopsis Error...
Demotrip is a Cooke triplet used throughout OSLO as a demonstration lens. It is good for this purpose because it contains the degrees of freedom needed to illustrated several optical principles, uses vignetting as a design variable, and is relatively straightforward to understand. The Cooke triplet...
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...
