Abstract
Apparatus and methods are described including adhering a first lens to a second lens such as to form a combined lens having a given optical design, by placing the first lens and the second lens in respective first and second pressure chambers with an adhesive layer disposed between the first lens and the second lens, bringing a convex surface of the first lens into contact with the adhesive layer, and bringing a concave surface of the second lens into contact with the adhesive layer. Other applications are also described.

A method, comprising:
- adhering a first lens to a second lens such as to form a combined lens having a given optical design, the adhering comprising:
- placing the first lens and the second lens in respective first and second pressure chambers, with an adhesive layer disposed between the first lens and the second lens, pressure within each of the first and second pressure chambers being independently controllable;
- bringing a convex surface of the first lens into contact with the adhesive layer, such that a central region of the convex surface of the first lens initially contacts the adhesive layer, and contact between the convex surface of the first lens and the adhesive layer subsequently radiates outwardly from the central region of the convex surface of the first lens, until the convex surface of the first lens becomes covered by the adhesive layer;
- and
- bringing a concave surface of the second lens into contact with the adhesive layer, such that a central region of the concave surface of the second lens initially contacts the adhesive layer, and contact between the concave surface of the second lens and the adhesive layer subsequently radiates outwardly from the central region of the concave surface of the second lens, until the concave surface of the second lens becomes covered by the adhesive layer.
An apparatus for adhering a first lens having at least one convex surface to a second lens having at least one concave surface, such as to form a combined lens having a given optical design, the apparatus comprising:
- a first pressure chamber configured to house the first lens, and second pressure chamber configured to house the second lens, pressure within each of the first and second pressure chambers being independently controllable;
- an adhesive layer disposed between the first and second pressure chambers;
- one or more mechanical pushing elements;
- and
- a computer processor configured:
- to drive one of the mechanical pushing elements to bring the convex surface of the first lens into contact with the adhesive layer, such that a central region of the convex surface of the first lens initially contacts the adhesive layer, and contact between the convex surface of the first lens and the adhesive layer subsequently radiates outwardly from the central region of the convex surface of the first lens, until the convex surface of the first lens becomes covered by the adhesive layer;
- and
- to drive one of the mechanical pushing elements to bring the concave surface of the second lens into contact with the adhesive layer, such that a central region of the concave surface of the second lens initially contacts the adhesive layer, and contact between the concave surface of the second lens and the adhesive layer subsequently radiates outwardly from the central region of the concave surface of the second lens, until the concave surface of the second lens becomes covered by the adhesive layer.
