## Abstract

An ophthalmic-lens holder (200) includes a plate (210) and three pads (250) which are mounted on the plate and rise up above the latter to offer free ends (271) via which they can bear the ophthalmic lens. At least one of the three pads is movably mounted on the plate.

## Claims

### Claim 1

A holder for an ophthalmic lens, comprising:
a plate, and
three studs which are mounted on the plate, the three studs projecting from the plate so as to have free ends by way of which the three studs are designed to support the ophthalmic lens, and at least one of the three studs is mounted so as to be able to rotate on the plate about a rotation axis,
wherein the free end of said at least one stud is located at a distance of between 5 and 25 millimeters from the rotation axis of the at least one stud, and
wherein the at least one stud (250) is free to pivot through one complete revolution about the rotation axis (A1),
wherein said at least one stud comprises a finger in the form of a stem, and a base to which the finger is fixed and which is mounted so as to be able to rotate on the plate, and
wherein said base is in the form of a transparent disk and is mounted in a corresponding circular housing in the plate.

### Claim 2 (depends on 1)

The holder as claimed in claim 1, in which the three studs are mounted so as to be able to rotate on the plate about three separate rotation axes.

### Claim 3 (depends on 1)

The holder as claimed in claim 1, in which said plate is transparent.

### Claim 4 (depends on 1)

The holder as claimed in claim 1, in which said plate has a planar face which reflects light.

### Claim 5 (depends on 1)

The holder as claimed in claim 1, wherein,
each of the three studs is rotatable on the plate about a different respective rotation axis,
a longitudinal axis of each said stud is located at a offset distance from the respective rotation axis of each said stud, and
each said stud is free to pivot through one complete revolution, at the offset distance, about the rotation axis of each said stud so that each said stud may occupy any angular position around the respective rotation axis of each said stud.

### Claim 6 (depends on 1)

The holder as claimed in claim 1, wherein,
each of the three studs is rotatable on the plate about a different respective rotation axis, and
a longitudinal axis of each said stud is located at a offset distance from the respective rotation axis of each said stud.

### Claim 7 (depends on 1)

The holder as claimed in claim 1, wherein,
each of the three studs is rotatable on the plate about a different respective rotation axis, and
a longitudinal axis of each said stud is located at a offset distance from the respective rotation axis of each said stud, and
each said stud is free to pivot through one complete revolution at the offset distance about the rotation axis of each said stud thereby to thereby vary distances between the three studs.

### Claim 8 (depends on 7)

The holder as claimed in claim 7, wherein, the studs are pivotable about the different respective rotation axis to vary a diameter of a circle (C2) circumscribed on the free ends of the three studs between 15 and 45 millimeters.

### Claim 9 (depends on 1)

The holder as claimed in claim 1, wherein,
each of the three studs is mounted on a different respective base at an offset distance from the respective rotation axis of each said stud,
the base of each of the studs is pivotably mounted to the plate about the different respective rotation axis of each stud, and
rotation of each base about the respective rotation axis of each stud pivots each said stud through one complete revolution at the offset distance about the rotation axis of each said stud.

### Claim 10 (depends on 1)

The holder as claimed in claim 1, wherein,
each of the three studs is mounted on a different respective base at an offset distance from the respective rotation axis of each said stud,
the base of each of the studs is pivotably mounted to the plate about the different respective rotation axis of each stud, and
each base is rotatable about the respective rotation axis of each stud to thereby pivot each said stud through one complete revolution at the offset distance about the rotation axis of each said stud to thereby vary distances between the three studs and to vary a diameter of a circle (C2) circumscribed on the free ends of the three studs.

### Claim 11 (depends on 10)

The holder as claimed in claim 10, wherein each base is comprised of a finger mounted on an upper surface of the plate and at the respective rotation axis of each said stud, the finger being rotatable about the respective rotation axis of each said stud.

### Claim 12 (depends on 10)

The holder as claimed in claim 10, wherein each base is comprised of a disk mounted in a circular recessed housing in an upper surface of the plate, each said disk pivoting freely in the circular recessed housing about the rotation axis of each said stud.

### Claim 13 (depends on 10)

The holder as claimed in claim 10, wherein, the studs are pivotable about the different respective rotation axis to vary the diameter of a circle (C2) circumscribed on the free ends of the three studs between 15 and 45 millimeters.

### Claim 14 (depends on 1)

The holder as claimed in claim 1, wherein the finger protrudes rectilinearly from the disk.
