WebMar 1, 1999 · The transition of the binary gravitational lens from the equal mass case to small (planetary) mass ratios q is studied. It is shown how the limit of a (pure shear) Chang-Refsdal lens is approached, under what conditions the Chang-Refsdal approximation is valid, and how the 3 different topologies of the critical curves and caustics for a binary … WebThe study of such diffracting lenses is known as binary optics. Micro-lenses in recent imaging chips have attained smaller and smaller sizes. The Samsung NX1 mirrorless system camera packs 28.2 million micro-lenses onto its CMOS imaging chip, one per photo-site, each with a side length of just 3.63 micrometer. WebThe binary optics technology uses techniques that were originally developed for manufacturing integrated circuits, whereby desired shapes are etched directly into the surface of an optical material.
