The present invention relates to an inspection system and more particularly to a system and method for inspection of wet ophthalmic lens, preferably in an automated lens manufacturing line. The inspection system provides for capturing multiple images of an ophthalmic lens using multiple cameras, each with a customized optical unit which may use wavelength filters, and the ophthalmic lens illuminated by multiple lighting modules each configured for a different wavelength, or a different polarization and triggered to strobe the illumination at the same instance or at different instances in the time domain. Suitable filters used in the optical module for each camera ensures appropriate images at different illuminating wavelength, especially when all the illuminations are strobed at the same time. Images captured and inspected by this configuration aids in improvement in method of inspection with enhanced degree of reliability and quality.

System and method for inspection of wet ophthalmic lens

An inspection system is provided. The system includes a rotating prism having a first end and a second end. The first end receives a first image area, such as a circular view, and rotates about a center point so as to cover a field of view area that is larger than the first image area, such as a larger circle that is defined by the smaller circle of view as it rotates around the center point. The second end remains centered on the center point and provides a viewing area that does not change in dimension. An image data system at the second end of the rotating prism generates image data as the prism rotates so as to generate two or more sets of image data that are contained within the field of view area.
