The present invention relates to optical power-limiting devices, and more particularly, to an optical power-limiting passive (self-adaptive) device and to a method for limiting solar power transmission in devices such as windows, using scattering level changes in a novel thermotropic composition that contains salt nano or microparticles embedded in a solid transparent host layer, where temperature change induces change in the refraction index of the matrix as well as of the embedded particles, creating a scattering layer, substantially reflecting the incident light thus limiting the amount of light passing through the window, green house covers, car sun roofs, solar panel windows and protection layers on housing roofs and walls, as a function of ambient temperature.

Temperature responsive optical limiter, composition and device

An energy efficient optical window has different optical properties when irradiated by solar light from front or back side of the window. The window is used to reflect most of the infrared light at summer times, leaving the interior cooler and to absorb most of the infrared light at winter times, making the interior hotter by heat transfer from the hot window pane. Mechanical reversal of the window, inside out, is used to apply the needed version for winter and summer. The window is coated with alternating thin metallic and dielectric layers that transmit most of the visible light while reflecting most of the infrared part of the spectrum when impinged by solar light on one side and transmit most of the visible light while absorbing most of the infrared part of the spectrum when impinged by solar light on the other side.

A system for facilitating a consumer's selection of customized color-changing lenses for eyewear, or windows, captures a digital color image of at least the face of the consumer and displays that color image to the consumer on a video display while superimposing a pair of lenses over the eyes.

The color of the superimposed lenses is changeable, in response to consumer-controlled inputs, over a range between (a) an initial color for the lenses when subjected to at least one of (i) a first predetermined temperature and (ii) a first predetermined light condition, and (b) a final color for said lenses when subjected to at least one of (i) a second predetermined temperature higher than said first predetermined temperature and (ii) a second predetermined light condition brighter than said first predetermined light condition.

An optical power-limiting passive (self-adaptive) device and method for limiting optical power transmission in lenses and windows, using layers of different photochromic compositions that exploit the full solar ultraviolet (UV) and short visible light spectrum. While a typical single photochromic material is activated by a UV band of wavelengths, e.g. 340 to 380 nm, adding a layer of photochromic material that is activated by an additional band of wavelengths, e.g., 380 to 420 nm, allows the efficient use of a wider band of solar UV and short visible light, e.g., 340 to 420 nm, thus enhancing the photochromic response to solar light.

Layered photochromic composition and device

An optical window-filter includes a thermochromic material and a light absorbing material that can be bonded chemically. Absorption of light by the light absorbing material generates heat that causes phase transformation of the thermochromic material. A filter for an infrared imaging system has detectors sensitive to radiation in an infrared transmission spectrum. The filter includes a thermochromic material and a light-absorbing material. Absorption of high-power radiation in the infrared transmission spectrum by the light-absorbing material generates heat that causes phase transformation of the thermochromic material to attenuate the high-power radiation while transmitting substantially unaffected low-power radiation in the infrared transmission spectrum.
