The project took them approximately an hour to ... At the other end is the objective lens, a concave-convex lens, which curves inward on one side and outward on the other. The convex side faces ...

Injection molding: a lot harder than you'd think! I picked up a benchtop injection molding machine to play with, and thought a "simple" double convex singlet lens would be a good first project.

These lenses are either convex - converging light, which magnifies an object, or concave, where light diverges making an object smaller. However, this new lens is 40 nm thin on a flat glass surface .

Plano- convex cylindrical lenses are typically used for illumination of slit and line detector arrays, laser projection, laser line focussing and anamorphic beam shaping. The spherical lens acts ...

Plano- convex cylindrical lenses are typically used for illumination of slit and line detector arrays, laser projection, laser line focussing and anamorphic beam shaping. If you have any demand, ...

Lenses are used in all optical instruments, like microscopes, telescopes, cameras, projectors etc. It is also of two type’s concave and convex lens. This article deals with mirror and lenses in ...
