Several simple column designs consisting of a ring-cathode gun unit combined with either a single magnetic or electric objective lens are presented.
It shows the end of the electric guide (the lens) on the left, the collision zone in the center, and the density normalisation region on the right.
The reticle collimation optics are situated at 90° to the optical path making lighting difficult, usually needing additional electric illumination, condensing lenses, etc.
He boasted that tiny electric motors adjust the lens 100 times per second, counteracting jittery human hands holding the phone.
A new lens from Alps Electric, measuring 1mm by 1mm, is said to have the ability to project a smartphone image on to a wall in the size of a 60-inch TV with HD resolution.
Sunflower-type graded photonic crystals (GPCs) are investigated and used to design the Luneburg lens for transverse electric (TE) and transverse-magnetic (TM) polarizations.
A medium whose refractive index increases with electric field intensity acts as focusing lens for a laser beam characterized by an initial transverse intensity gradient.
A concentrating photovoltaic (CPV) system with a steady electric output adopting an electrically tunable concentration ratio of the liquid crystals (LC) lens is demonstrated [6].
Stanley Kubrick spent a fortune and "minimised the use of electric light by using the fastest lenses available" for the candlelit Barry Lyndon.
