摘要: A method for coating an optical substrate with an anti-reflection multilayered stack is provided. The method includes depositing a stack of dielectric layers having alternate index of refraction over a substrate, to form an anti-reflective coating. The method also includes depositing a first layer of low refractive index material on top of the stack of dielectric layers, etching the first layer of low refractive index material with a solvent at a selected temperature, and conformally depositing a sealant material over the first layer of low refractive index material to complete the anti-reflective coating. A headset for virtual reality, augmented reality, or mixed reality applications including optical components having an anti-reflection coating fabricated per the above method is also provided.

摘要: A method of forming a low reflectivity coating on an optical surface for wide angle of incidence is provided. The method includes depositing a low refractive index layer of material on a stack of dielectric layers, depositing a hydrophobic compatible material on the stack of dielectric layers, forming a blend interface layer on the stack of dielectric layers, the blend interface layer including a portion of the low refractive index layer of material and a portion of the hydrophobic compatible material, and depositing a hydrophobic layer of material adjacent to the blend interface layer. A physical vapor deposition chamber to perform the above method is also provided.

摘要: An optical device includes a first optically dimmable switch for providing a first transmittance while the first optically dimmable switch is in a first state and providing a second transmittance distinct from the first transmittance while the first optically dimmable switch is in a second state distinct from the first state. The optical device also includes a dynamic heat source thermally coupled with the first optically dimmable switch. The dynamic heat source is at a first temperature at a first time and is at a second temperature distinct from the first temperature at a second time mutually exclusive from the first time. The optical device may operate as an optical dimming device, which may be used in head-mounted display devices or as dimmable windows or shutters.
