Optical element, optical apparatus, image pickup apparatus, and method for producing optical element
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.
Method of manufacturing a lens with an embedded foil
A lens with an embedded foil is produced, comprising the steps of providing a first mold and a second mold, providing a functional foil, positioning and attaching the functional foil on the first mold, aligning the second mold relatively to the first mold, sealing the mold cavity between the first mold and the second mold, and filling a curable monomer mixture into the mold cavity, wherein either the molds are heated before the alignment step or the molds are heated after the sealing step and the following filling step is conducted with a heated monomer, or the heating of the molds follows the filling step of the UV curable monomer, followed by a UV curing step of the heated UV curable monomer mixture within the heated mold cavity.
TUNEABLE OPHTHALMIC LENS
A tuneable contact lens (100), wherein the contact lens comprises a central region (108). The central region has a circumferential wall and an anterior surface having an external curvature. The contact lens also comprises an inflatable ring (106) arranged around the circumferential wall of the central region, and at least one fluid reservoir (104) in fluid connection with the inflatable ring. The at least one fluid reservoir comprises a pump. When fluid is pumped from the at least one fluid reservoir to the inflatable ring, the inflatable ring inflates and the external curvature of anterior portion of the central region is changed.
