Influence of the Position of the Stop in a Lens System
Abstract
Stop in a lens system is important because it directly determines the light interaction with the edge of the aperture of the lens surface, which exsited physically in the manufactured lens system. Therefore, different positions of the stop might have an influence on the Point Spread Function (PSF). VirtualLab Fusion provides an ease way to investigate this influence by considering the diffraction, if necessary, from the edge of each surface, especially with inclined illumination.

Analyzing High-NA Objective Lens Focusing
High-NA objective lenses are widely used in optical lithography, microscopy, etc. Consideration of the vectorial nature of light in the simulation of the focusing is of great importance.
