    Abstract: An electronically dimmable optical device, including, in sequence, an active absorbing polarizer; a first static reflective polarizer; an active polarization rotator; and a second static reflective polarizer; configured so that the reflectivity and/or transmissivity of the device can be controlled (increased or decreased) by application of a voltage across the active absorbing polarizer and/or the active polarization rotator. One or more polarization levels can be selected by controlling the voltage at the active absorptive polarizer such that setting the active absorptive polarizer to a selected polarization level determines the brightness of an image produced by the device.

    Abstract: 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 CCS and a photopic transmission PTCS of 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 CD1 and a photopic transmission PTD1 lower than PTCS, and iii) a second darkened state having chromaticity CD2 and a photopic transmission PTD2 that is lower than PTD1. CD1 and CD2 each fall within chroma 2 when their respective PT values correspond to a Munsell value of 5 or less.

    Abstract: 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.

    Abstract: An optical device with one or more spatially variable optical response characteristics is disclosed. The optical device includes a cell including a liquid crystal material contained between a pair of substrates, each substrate having a transparent conductive layer provided thereon. An electrode connection contacts each transparent conductive layer. A driving signal source is in electrical communication with each electrode connection for application of a driving signal to the cell. An applied driving signal to the electrode connections from the driving signal source creates a voltage gradient in a gradient direction along the pair of transparent conductive layers leading away from the electrode connections. The voltage gradient is received by the liquid crystal material to produce a gradient in at least one optical response characteristic across at least a portion of the device.

    Abstract: Disclosed is an optical assembly having a first variable transmission layer comprising a first electro-optically active material between a first pair of substrates, a second variable transmission layer comprising a second electro-optically active material between a second pair of substrates, and an electronically switchable birefringent layer, that is capable of altering the phase of incident light, situated between the first and second variable transmission layers. The layers are arranged such that light passing through the optical assembly can be altered based on the voltage applied to each layer. The light transmission levels can be altered between maximally transmissive, minimally transmissive, and semi-transparent levels between the maximally and minimally transmissive levels.
