A plano-concave cylindrical lens is used to expand light in on axis. A negative cylindrical lens is able to diverge collimated input light away from a line. Plano-concave cylindrical lenses are used ...

Provided in a water-clear cylindrical T1-3/4 leaded package, daylight-visible LEDs have a concave lens for more even light emission. Offering a viewing angle of 110°, the LEDs are available in green, ...

A cylindrical optical lens is typically used to focus, condense or expand incoming light. A cylindrical optical lens has one cylindrical surface, causing light to be focussed in a single dimension or ...

The company's latest LEDs exploit a 5-mm, concave-cylindrical (T1-3/4) design that allows them to emit light that is as bright at their edges as it is in the center. Concave lenses are said to improve ...

Although many studies on graded index (GRIN) lenses have been reported over the past several years, it is extremely difficult to find reports that have used polymer GRIN lenses in an atmosphere ...
