EQUIPMENT FOR CAPTURING THE CONTOUR, MARKINGS, BORES, MILLINGS AND ETCHINGS OF AN OPHTHALMIC LENS OR TEMPLATE LENS FOR GLASSES

Abstract

Equipment for capturing the contour, markings, bores, millings and etchings of an ophthalmic lens or a template lens for glasses. Equipment for capturing the contour, markings, bores, millings and etchings of an ophthalmic lens or a template lens for glasses comprising lighting means (11) that produce a beam of parallel rays of light that can produce a projection, image capturing linear means (15), a translucent support (3) arranged between lighting means (11) and capturing means (15), and control means that digitalize and process the projection obtaining a flat representation of the contour, markings, bores, millings and etchings. The lens or template lens are placed on translucent support (3) and a high quality projection of the lens or template lens is formed on support (3) without having to prepare the lens or template lens beforehand by painting it or the like.

Claims

1. Equipment for capturing the contour, markings, bores, millings and etchings of an ophthalmic lens or template lens for glasses characterized in that it comprises: lighting means (11) suitable for producing a beam of parallel rays of light that can produce a projection,image capturing linear means (15),a translucent support (3) arranged between said lighting means (11) and said image capturing linear means (15), with one front face, facing lighting means (11) and one rear face facing image capturing linear means (15), where said front face is suitable for supporting said ophthalmic lens or template lens for glasses and receiving said beam of parallel rays of light that can produce a projection, so that when an ophthalmic lens or template lens for glasses is placed on said translucent support (3) a projection of said lens or template lens for glasses is formed on said translucent support (3), andcontrol means suitable for digitalizing said projection received by said image capturing linear means (15) and for processing said projection obtaining a flat representation of said contour, markings, bores, milling or etchings.

2. Equipment according to claim 1, characterized in that it has a curvature measurement system (5) of said lens or template lens.

3. Equipment according to claim 2, characterized in that said curvature measurement system (5) has communication means suitable for supplying the value of said curvatures to said control means.

4. Equipment according to any of the claims 1 to 3, characterized in that said control means have calculation means suitable for calculating the 3D shape of said lens on the basis of said projection and said curvatures.

5. Equipment according to any of the claims 1 through 4, characterized in that said lighting means (11) comprise a spot light source (17) and a collimator.

6. Equipment according to any of the claims 1 through 4, characterized in that said lighting means (11) comprise a light source (17) made up of various spot light emitters and a collimator (19).

7. Equipment according to any of the claims 1 through 6, characterized in that said image capturing linear means (15) comprise scanning speed and resolution adjustment means.

8. Equipment according to any of the claims 1 through 7, characterized in that said translucent support (3) is made up of a transparent sheet and a translucent sheet.

9. Equipment according to any of the claims 1 through 8, characterized in that it comprises display means (13) suitable for viewing said projection, said digitalized projection, control instructions and results.

10. Equipment according to any of the claims 1 through 9, characterized in that it comprises data and command input means.
