An optical element includes a first substrate having a first surface, a resin member disposed on the first surface, and a second substrate disposed above the resin member with a joining member interposed therebetween. The resin member has a first region contacting the joining member and a second region surrounding the first region and not contacting the joining member. An inclined portion having a thickness increasing from a starting point located in the second region toward an outer circumference of the resin member, is disposed in the second region. A tangent of the first surface, orthogonal to a normal of the first surface passing through the starting point, and a straight line passing through the starting point and a point at which the inclined portion has a largest thickness, form an angle of 25° or more and 45° or less.

A light deflector, a method of manufacturing the light deflector, and an image projector. The light deflector and the method includes forming a first wafer provided with a plurality of movable mirror units, bonding the first wafer to be sandwiched between a second wafer on which a plurality of base units are formed and a third wafer on which a plurality of spacers are formed, bonding a fourth wafer on which a plurality of transparent members are formed on the third wafer, bonding a plurality of polyhedron light-beam adjusters on the fourth wafer such that one of the plurality of polyhedron light-beam adjusters and the movable mirror unit become a pair, and cutting a wafer layered product of the first to fourth wafers for each area in which the light deflector is formed. The image projector includes the light deflector, and an image is projected by optical scanning.

The invention relates to a molding tool having a tool upper part (10) and a tool lower part (20), having a glass pane (30) arranged between tool upper part (10) and tool lower part (20) and at least one sheet metal insert part (32; 321, 322, 323, 324) that can be connected to the glass pane (30) by means of foam overmolding (36) made of plastic. For an increased process reliability when connecting sheet metal insert parts (32; 321, 322, 323, 324) to panes (30), the invention provides that at least one sensor (40) for detecting the position of the sheet metal insert part (32; 321, 322, 323, 324) is arranged on the tool upper part (10) and/or the tool lower part (20) on the side of the glass pane (30) that is located opposite the at least one sheet metal insert part (32; 321, 322, 323, 324).

Method and composition for switchable panels are disclosed. Switchable films are placed between glass and liquid resin is injected between the glass and cured. The panels may be used for a wide variety of applications.

A method for manufacturing a grazing incidence optical element is provided that includes the steps of: providing a mandrel having a surface with a profile complementary to the profile of an optical surface of the optical element to be made; adhering at least one glass sheet to the mandrel to define the optical surface; and depositing a carbon fiber reinforcing material on an outer surface of the glass sheet to create a shell solidly connected to the glass sheet.

A method of manufacturing a plurality of optical elements includes providing a first wafer (200) having lower alignment features (192) arranged on a first surface of the substrate, providing a second wafer (201) comprising, on a replication side, a plurality of replication sections, each replication section defining a surface structure of one of the optical elements, the second wafer (201) further comprising upper alignment features (194) protruding, on the replication side, further than an outermost feature of the replication sections, depositing liquid droplets (196) on the first side of the first wafer (200), and bringing the second wafer (201) and the first side of the first wafer (200) together, with liquid droplets (196) between the first wafer (200) and the second wafer (201), the upper alignment features (194) contacting the liquid droplets (196) on the lower alignment features (192) on the first side of the first wafer (200), and thereby causing the second wafer (201) to align with the first wafer (200) by capillary action.
