Thread: Scientists invent lens five times thinner than a sheet of paper

    Default Scientists invent lens five times thinner than a sheet of paper

    I don't know if this makes a difference in the future of lens designs but will there be a 10-1000f2.8 zoom in the future?

    Scientists at Canada's Universite Laval have invented a lens that is five times thinner than a piece of paper and can zoom without using mechanical parts. The lens is created by adding a small quantity of photosensitive material to a liquid crystal cell. When a weak electrical current is applied, the crystals realign differently from those in the periphery and thus take on the shape and behavior of a lens. The researchers have been able to modify the lens’ focal distance from 1.6 to 8 meters in a few milliseconds by increasing the voltage from 1.5 to 4.5 volts.

    guess the optical quality will not be good enough for a camera any time soon.

    it's a start. It'll improve.. plasma tvs were first invented in the late 1970s but didn't take off becos of the very limited field of view and huge power comsumption. It became a reality today.

    Soon the lens will take off.. 'soon'..
