System for checking centration of lens surfaces of aspheric lens
First Claim
1. A system for checking centration of opposite lens surfaces of an aspheric lens in a lens module, the system comprising:
- a light-emitting device for emitting light;
a lens holder for positioning the aspheric lens in a light path of the light emitted from the light-emitting device;
an image processing device for receiving the light which is emitted from the light-emitting device and has passed through the aspheric lens, producing an image and showing the image, wherein a quality of the image shown by the image processing device determines a tilt degree of the aspheric lens.

Abstract
A system for checking centration of lens surfaces of an aspheric lens includes a light-emitting device, a lens holder and an image processing device. The light-emitting device emits a light. The lens holder positions the aspheric lens in a light path of the light emitted from the light-emitting device. The image processing device receives the light which is emitted from the light-emitting device and has passed through the aspheric lens, and produces an image and shows the image. A quality of the image shown by the image processing device determines a tilt degree of the aspheric lens.

7. A system for checking optical alignment between an aspheric lens and a main optical axis of a lens module, the lens module having the main optical axis and the aspheric lens disposed in the main optical axis, the system comprising:
-
a laser source for emitting a laser beam; a holder for holding the lens module in position; a first aperture for being disposed between the laser source and a first side of the lens module; an image sensor for being disposed at an opposite second side of the lens module and capturing an image associated with the laser beam; and a display screen electronically coupled to the image sensor for displaying the image thereon. - View Dependent Claims (8, 9, 10)
