A spyglass with a plano-convex lens that focuses at 12 inches and a ... each of which comes into focus at a different point on the optical axis—hence the color fringes seen in refractors.

In a study published in Optica, these researchers demonstrate the new method by using it to make a millimeter-sized plano-convex optical lens with an imaging performance similar to a commercially ...

and subsequently employed to demonstrate the fabrication of micro-optical devices by thermal imprinting. Using 3D-printed fused silica templates, we show that concave as well as convex lens ...

Argyle International manufactures optics. All of our optical components are held to the highest standards, always at substantial saving. Argyle makes a variety of components from plano-convex lenses ...

They have the advantage of dramatically reducing size and thickness compared to conventional convex optical lenses, making them a focus for next-generation devices in optical system fields such as ...
