OPTICAL ARTICLE HAVING A MULTILAYERED ANTIREFLECTIVE COATING INCLUDING AN ENCAPSULATED METAL FILM
This invention relates to an optical article comprising a transparent substrate with a front main face and with a rear main face, at least one of the main faces being coated with a multilayered antireflective coating comprising at least one low refractive index layer (LI) having a refractive index lower than 1.55 at 550 nm, named hereafter first LI layer, one first high refractive index layer (HI) having a refractive index higher than or equal to 1.55 at 550 nm, named hereafter the first HI layer, and one encapsulated metal film (EMF) comprising a metal island layer (MIL) that is encapsulated between a first layer (L1) and a second layer (L2), said first layer (L1) and said second layer (L2) being both composed of at least one dielectric material, characterized in that said—the first layer (L1) is a second LI layer having a refractive index lower than 1.55 at 550 nm and has a physical thickness equal to or higher than 10 nm, —the metal island layer (MIL) has plasmonic effects and has an effective thickness ranging from 0.2 nm to 4 nm, preferably ranging from 0.5 to 4 nm, —the second layer (L2) has a physical thickness equal to or higher than 10 nm, wherein said multilayered antireflective coating has a mean light reflection factor in the visible region Rv on the front face and/or on the rear face of said optical article that is equal to or lower than 2.5% for at least an angle of incidence lower than 35°, preferably for an angle of incidence of 0°. The absorption of said AR stack is mainly due to said MIL layer.
Multi-pane electrochromic windows
Window units, for example insulating glass units (IGU's), that have at least two panes, each pane having an electrochromic device thereon, are described. Two optical state devices on each pane of a dual-pane window unit provide window units having four optical states. Window units described allow the end user a greater choice of how much light is transmitted through the electrochromic window. Also, by using two or more window panes, each with its own electrochromic device, registered in a window unit, visual defects in any of the individual devices are negated by virtue of the extremely small likelihood that any of the visual defects will align perfectly and thus be observable to the user.
METHOD FOR MANUFACTURING DECORATIVE MEMBER, AND DECORATIVE MEMBER
The present disclosure relates to a method for manufacturing a decoration element, the method including depositing a light reflective layer having a structure of two or more islands separated from each other on one surface of a light absorbing layer; and dry etching the light absorbing layer using the island as a mask, wherein a resistance value of the decoration element after the dry etching of the light absorbing layer increases by two times or more compared to before the dry etching of the light absorbing layer.
Motor vehicle headlamp
The invention relates to a motor vehicle headlamp (8) comprising a vehicle headlamp housing (9), an at least sectionally transparent cover pane (10) that closes the vehicle headlamp housing (9), a light source (11) that is accommodated in the vehicle headlamp housing (9) and serves for radiating light through the cover pane (10), and at least one motor vehicle design element (3) that is accommodated in the vehicle headlamp housing (9), wherein the at least one motor vehicle design element (3) comprises a dimensionally stable substrate (1) with at least one coated side.
