A multi-color variable transmission optical device (“MC-VTOD”) includes a first cell having a first electro-optic material provided between a first pair of substrates and a second cell having a second electro-optic material provided between a second pair of substrates. The first electro-optic material can changing from a state of higher light transmittance to a state of lower light transmittance in a first wavelength region upon a change in an electric field applied across the first electro-optical material. The second electro-optic material is capable of changing from a state of higher light transmittance to a state of lower light transmittance in a second wavelength region different from the first wavelength region upon a change in an electric field applied across the second electro-optical material. The MC-VTOD is switchable between i) a clear state wherein the first cell and second cell are in the state of higher light transmission, ii) a first tinted state wherein the first cell is in a state of lower light transmittance and the second cell is in a state of higher light transmittance, and iii) a colorimetrically neutral darkened state wherein at least the second cell is in a state of lower light transmittance. At least the first cell is characterized by a narrow band absorption of 175 nm or less in its state of lower light transmittance.

A variable transmission optical device ('VTOD') includes first and second cells in optical communication, each cell having an electro-optic material capable of changing from a state of higher light transmittance to a state of lower light transmittance upon a change of an electric field applied across the electro-optic material. The VTOD is switchable between i) a clear state having chromaticity Cand a photopic transmission PTof at least 20% wherein the first cell and second cell are each in the state of higher light transmission, ii) a first darkened state having chromaticity Cand a photopic transmission PTlower than PT, and iii) a second darkened state having chromaticity Cand a photopic transmission PTthat is lower than PT. Cand Ceach fall within chroma 2 when their respective PT values correspond to a Munsell value of 5 or less.

Color-preserving variable transmission optical device

A laser protection variable transmission optical device ('LP-VTOD') includes first and second cells, each capable of changing from a state of higher light transmittance to a state of lower light transmittance. The first cell is characterized by a narrow band absorption having a first peak absorption wavelength and a first FWHM of 175 nm or less, and the second cell is characterized by a narrow band absorption having a second peak absorption wavelength and a second FWHM of 175 nm or less. The first peak absorption wavelength may be the same or different than the second peak absorption wavelength. The LP-VTOD is capable of switching from a clear state to a darkened state having a darkened state transmittance % Tthat is equal to or less than 10% for at least one of the first or second peak absorption wavelengths.

Laser-protection variable transmission optical device

A visual impairment device includes a power supply, an intense light source having two or more beams of intense light with different peak wavelengths and a wavelength bandwidth less than 50 nm, a modulator and a control circuit. The modulator operates to modulates the two or more beams of intense light to produce a spatial array such that at least one of the beams used to produce the spatial array has the requisite irradiance to cause visual impairment. In some examples, the beams of intense light are laser beams. Also included are methods of using the device to cause visual impairment of an intruder who enters a visual impairment zone created by said device.

Light shield device

A visual impairment device includes a light source, a modulator, and a controller. The light source capable of generating two or more high intensity light beams having different peak wavelengths, wherein at least one of the light beams has a wavelength bandwidth of less than 100 nm. The modulator modulates the two or more beams of intense light to produce a spatial array comprising a first array of first light beams having a first peak wavelength and a second array of second light beams having a second peak wavelength different from the first wavelength. The controller includes control circuitry for controlling the light source, the modulator, or both. The spatial array is projected into a space such that a lateral distance of at least one first light beam to a second light beam is in a range of 40-110 mm within at least one area of the space.

Device for disrupting binocular vision

A light emitting photonic bandgap (PBG) material, and devices uses the same, having (a) a polymer network exhibiting a non-uniform pitch; (b) a small molecule liquid crystal material with a birefringence&#x3e;0.04; and (c) one or more light emitting dyes having a low triplet state absorption. The light emitting PBG material has a defect-induced density of states enhancing feature at a wavelength that overlaps the emission spectrum of the light emitting dye. Excitation of the light emitting PBG material by a light source causes a directional electromagnetic emission from the light emitting material. The PBG material, and device, are capable of emitting continuous wave laser light as a result of excitation by a low-power incoherent light source.
