Thin-film materials with variable optical properties




For solids and liquids, the reversible transformations of molecular structure, symmetry and energy band are commonly seen. Such reversible transformations may take place gradually or suddenly as far as we know. Sudden reversible transformation is very significant. It may be induced electrically or thermally, under pressure or upon exposure to ultraviolet – visible radiations. The materials that respond to such inductions within the spectrum of visible lights are electrochromic material, thermochromic material, pressure chromomic material and photochromic material respectively.

Electrochromism is a visible change that is associated with the electrochemically-induced oxidation-reduction reaction at a low voltage and characterized by reversible transmissivity or reflectivity. Its typical DC voltage is about +/1V. Chromic materials are deposited on transparent conductive electrodes, e.g. glass coated with SnO2: F or indium-tin-oxide. Immerse the electrode in an appropriate electrolyte that contains alkali ions. In case of organic thin films, the electrode is immersed in an appropriate anion electrolyte. The representative materials include WO3 and MO3. Thermochromic materials change color with the changes of surrounding environment of metal ions due to changes in visible light spectrum of some interim metal compounds. The representative materials include VO2, Ag2S and FeS.

Pressure-sensitive chromic materials may have rapidly changing optical properties due to pressure-induced volumetric changes and structural transformations between semiconductor and metal. The representative materials include: SmS and EuTe.

Photochromic materials are some thin-film materials that have visible color changes subject to different wavebands of lights like visible lights and ultraviolet rays. The representative materials include: WO3, MoO3 and AgCl-CuCl.


Wonder who will take over this principle already used in the electronic industry and trumpet it as their latest optical invention ?????????????

I think that I have seen that technology developed by a company from Korea and they asked for $2,000 a pair in retail!

Interesting

Sort of like this..

Except that the PixelOptics emPower! lens uses the voltage to change the refractive index, instead of the tint.

Liquid Crystal technology.

Whatever happened to alpha micron?

I assume the next invention will be the RYSER lens for WISER patients

Akari AX-11 Top Product of 2013 Dealer Expo

Published on: March 11, 2013 by alphamicron
AX-11 Named Top Product of 2013 Dealer Expo
The Akari AX.11 features e-Tint, a patented liquid-crystal technology enabling the insert to change from light to dark in less than 1/10th of a second. Riders can control the tint of the insert manually with a switch attached to the side of the faceshield or by programming the device to automatically darken/lighten via its light-sensing photocell. The inserts are powered by a rechargeable lithium battery with a 20-hour working time limit. The AX.11 should be on sale this March with a price tag of $150.
