Optical stacks are described that include a reflective polarizer disposed between an infrared reflector and an infrared absorber.

The present disclosure relates to a laminated glazing comprising a first glass substrate and a second glass substrate laminated together having first and second polymer intermediate films therebetween, and a layered film laminated between the polymer intermediate films, wherein the layered film comprises at least three carrier layers positioned parallel to one another with a second carrier layer positioned between first and third carrier layers, wherein a first surface of the first carrier layer is coated with a first transparent conductive coating and a first surface of the second carrier layer is coated with a second transparent conductive coating, wherein the first surface of the first carrier layer faces the first surface of the second carrier layer, and wherein a second surface of the second carrier layer is coated with a third transparent conductive coating and a first surface of the third carrier layer is coated with a fourth transparent conductive coating, wherein the second surface of the second carrier layer faces the first surface of the third carrier layer; a first switchable layer positioned between the first and second carrier layers; and a second switchable layer positioned between the second and third carrier layers.

Provided is a laminate which can not only control the amount of external light transmitted, but can also be used as a mirror. A laminate 1 comprises: a first liquid crystal member 100; a reflection type polarizing member 200; and a second liquid crystal member 300. The first liquid crystal member has first liquid crystal cells with changing orientation states, and a first absorption type polarizing member. The first liquid crystal cells can be switched: between a mode where one type of polarized light of the incident light is blocked and the other type of polarized light is transmitted, and a mode where one type of polarized light of the incident light is blocked and the other type of polarized light is shifted and then transmitted; between a mode where the incident light is transmitted as-is, and a mode where one type of the polarized light is blocked and the other type of polarized light is transmitted; and between a mode where one type of polarized light of the incident light is blocked and the other type of polarized light is transmitted, and a mode where one type of polarized light of the incident light is transmitted and the other type of polarized light is blocked. The reflection type polarizing member receives the light transmitted by the first liquid crystal member, transmits one type of polarized light of the incident light, and reflects the other type of polarized light. The second liquid crystal member has second liquid crystal cells with changing orientation states, and a second absorption type polarizing member. When the reflection type polarizing member has transmitted polarized light, the second liquid crystal cells can be switched between a mode where the polarized light is blocked and a mode where the polarized light is transmitted.

Methods for preparing multi-layer optical laminates include placing an optical film that is free form an adhesive layer between first and second glass substrates that are free of an adhesive layer, placing this laminate under vacuum, and then heating the laminate under pressure to a temperature above the softening temperature of the optical film. The glass substrates are free of an adhesive layer but may include a silane surface treatment. The resulting multi-layer laminate is optically clear and does not show scattering of reflected light by the optical film.

An optical device is provided in the present application. The present application provides an optical device capable of varying transmittance, and such optical device can be used for various applications, such as eyewear, for example, sunglasses or AR (augmented reality) or VR (virtual reality) eyewear, an outer wall of a building or a sunroof for a vehicle.
