Using 3D-printed fused silica templates, we show that concave as well as convex lens structures can be obtained at high precision by remelting the glass without trading-off on material quality.

Technically, the glasses have a distance sensor embedded ... The design is small, light, can produce plano-convex or plano-concave lenses, and can do so quickly (within 15 ms) and with low ...

A lens is a specially shaped pieces of glass or transparent plastic, that is used to focus light. A convex lens is made from a transparent material that bulges outwards in the middle on both sides.

Several other lenses are demonstrated, including a cylindrical convex lens, but these are only planoconvex lenses, or lenses that are flat on one side. Biconvex lenses can be constructed by gluing ...

To test the new method, the researchers first created a simple plano-convex lens and showed that it had an imaging resolution comparable to a commercial glass lens with the same physical dimensions.

A type of glasses-free 3D (autostereoscopic) technology that separates the image into left and right frames. Lenticular 3D uses a convex lens to direct the eyes appropriately. Left and right ...
