Abstract: 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 % TDS-P that is equal to or less than 10% for at least one of the first or second peak absorption wavelengths.

Abstract: Provided is a liquid crystal light variable device having a liquid crystal cell, comprising a mixture of a liquid crystal material and one or more dichroic dyes interposed between a first and a second substrate, each substrate having a conductive layer disposed thereon. The device further includes a voltage supply or controller coupled with the conductive layers for application of a voltage waveform across the liquid crystal cell. The liquid crystal cell is configured so that based on the voltage waveform applied, the device transitions between a low-haze low-tint state (“clear state”), a low-haze high-tint state (“tinted state”), and a high-haze high-tint state (“opaque state”). The high-haze state is caused by dynamic scattering in the liquid crystal-dye mixture.

The optical device is capable of switching from a clear state having a clear state transmittance % TCS-P to a darkened state having a darkened state transmittance % TDS-P, wherein a change between % TCS-P and % TDS-P corresponds to an optical density difference (ΔOD) of greater than 0.5 OD for at least one of the first or second peak absorption wavelengths. Both the first and second peak absorption wavelengths are in a range of 380-780 nm.

Abstract: A switchable one-way mirror device dividing first and second spaces includes a switchable electro-optic layer facing the second space and configured to be electronically switchable between a transmissive state and one or more opaque states, and a partial reflector incorporated within or adjacent the switchable electro-optic layer and facing the first space and configured to partially reflect light. The switchable one-way mirror partially transmits a first light going from the first space to the second space, and a second light going from the second space to the first space. When the switchable electro-optic layer is in an opaque state, transmission of light through the device is reduced thereby changing the ratio between the transmission of the second light to the first space and the reflection of the first light by the partial reflector resulting in reduced visibility of the second space by a viewer in the first space.

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.
