WebFeb 1, 2011 · - bug fix. Toric RayTrace - ray missing surface. If a ray cannot intersect with a surface [ignoring apertures], then a flag is set and the ray trace ceases. For toric raytraces, this ‘ray miss’ was properly detected, but the flag was not set, so the raytrace continued spuriously. The flag is now set appropriately. WinLens3D 1.1.7 - enhancement. WebThe convex surface is given as z ( x ) = ( 64 ) 10 − 4 − ( x − 0 . 15 ) 2 (units in meters). The indexes of refraction are 1.5 inside the lens and 1.0 for the optical media. In Fig. 4, the ...
