When I visited the 83-year-old artist recently in the five-story cast-iron SoHo building where he lives and works, his parabolic lenses littered the living room.

The parabolic lenses are under 20 inches in diameter and around six inches deep, and the horizontal lenses are just slightly larger in diameter.

The device included a parabolic lens with a 27 µm focal length and an axicon with a cone of radius 30 µm and a height of 23 µm. The parabolic lens was designed to align the widely diffracted light ...

The filament of the lamp is placed in the precise focal point of the parabolic reflector so that the light rays exiting the lens are parallel. This creates a focused beam of illumination from a ...

Featuring a unique surface emitter technology and parabolic lens for a narrow ±3º angle of half intensity, the VSLY5850 85-nm infrared (IR) emitter delivers a radiant intensity of 600 mW/sr at a ...

The filament was formed by the reflection of radiation from the parabolic lens.

Some might take an audio recorder and parabolic microphone with them for focused sound recording, but having to work a camera and such audio equipment on their own could prove challenging.

The device included both a parabolic lens for light collimation and a helical axicon lens that twists the light. This turns light exiting the fiber into a twisted Bessel beam.

Parabolic reflectors for solar applications are nice stuff, and making your own is a great project in itself. One of the easiest ways we have seen is that of [GREENPOWERSCIENCE], who uses nothing m… ...
