A telescope, mirror assembly and method of forming an aspheric mirror is disclosed. The telescope includes the mirror assembly which has a substantially spherical surface contour in a relaxed state. A plurality of actuators distributed substantially along an outer edge of the mirror is configured to apply a load to the mirror assembly to deform the mirror to obtain a substantially aspheric surface contour.

A method of forming a mirror reflector sub-assembly suitable for use in an exterior rearview mirror assembly of a vehicle includes providing a glass substrate having a first surface and a second surface. Glass is physically removed from a portion of the second surface of the glass substrate to form a curved recess locally thereat. The second surface of the glass substrate is coated with a mirror reflector via a vacuum deposition process. When used in an automotive exterior rearview mirror assembly, the mirror reflective element provides a principal reflector portion and an auxiliary reflector portion to a driver of the vehicle who views the mirror reflective element when normally operating the vehicle. A mirror back plate is formed in a plastic molding operation and a heater pad is disposed between the coated second surface of the glass substrate and a first side of the mirror back plate.
摘要:
Films, sheets or profiles useful as optical reflectors may be prepared by extruding a melt-processable acrylic resin composition comprised of acrylic polymer, white pigment and, optionally one or more additives such as impact modifiers, matting agents, UV stabilizers, antioxidants and processing additives onto a layer of ABS, acrylic or other thermoplastic. Alternatively, a monolithic film or sheet or profile useful as an optical reflector is obtained by forming the acrylic resin composition using a melt-processing technique such as extrusion or injection molding without a substrate layer.

A mirror reflector sub-assembly for a vehicular exterior rearview mirror assembly includes a mirror reflective element having a glass substrate. A principal reflector portion has a first radius of curvature and an auxiliary reflector portion includes a curved recess having a second radius of curvature smaller than the first radius of curvature. The curved recess is established at the second surface of the glass substrate by physical removal of glass from a portion of the substrate. The mirror reflective element is supported at a side of a mirror back plate and an opposing side of the mirror back plate is adapted for attaching the mirror back plate to a mirror actuator of an exterior rearview mirror assembly equipped with the mirror reflector sub-assembly. A heater pad is disposed at the second surface of the glass substrate between the mirror reflective element and the mirror back plate.

A colored mirror includes a transparent substrate and a reflective layer, including a coloring layer between the substrate and the reflective layer, the coloring layer including a matrix and a colorant. Furthermore, a process for preparing a mirror including a transparent substrate and a reflective layer, a coloring layer between the substrate and the reflective layer, the coloring layer including a matrix and a colorant, includes the production of the coloring layer on the substrate then the deposition of the reflective layer on the coloring layer.
摘要:
A molded dichroic mirror and method of manufacture thereof. The dichroic minor may be molded from polysiloxane or lithia potash borosilicate and may be coated to reflect an infrared signal and configured to transmit a radio frequency signal between 33 GHz and 37 GHz.
摘要:
A reflective cover molding method and a reflective cover manufactured thereof are disclosed. The reflective cover molding method comprises the steps of: providing a metal substrate; setting the metal substrate on a substrate mold, and punching the metal substrate by a pressure to form a circular substrate; propping the circular substrate onto a fixed mold with a prop; jointly rotating the fixed mold and the circular substrate, applying a pressure by a spinning roller to attach the circular substrate, and applying a pressure to spin out a molded cover; setting the molded cover onto a shaped mold, and punching the molded cover by a pressure to form an optical structure surface on the molded cover; and punching the molded cover to remove a bottom hole to form the reflective cover, so as to accelerate production rate and enhance product quality, stability and precision.
