An inspection system and method to detect the presence or absence of ophthalmic lenses in a plastic shell just before the seal is applied comprising a high resolution imaging device suitably integrated with an optical module; a UV illumination module suitably mounted below the ophthalmic lens holder; a Visible LED based Top lighting module suitably mounted on Top of the Ophthalmic lens holder; the inspection system which captures images of the lens immersed in a saline solution in a the plastic shell; analyzing the image and determining the characteristics of the lens perimeter and the optical center; making a decision to reject the inspected item if the analyzed image indicates the presence of a flipped, multiple and folded lens or the absence of the lens; making a decision to accept the inspected item, if the analyzed image indicates the presence of a single lens positioned in the correct orientation.

Contact lens inspection in a plastic shell

An inspection system to inspect the consistency and thermal seal quality of blister packages, the system comprising an illumination module and a color imaging device suitably integrated with an optical module. The blister packages that are thermally sealed are sequentially presented to the color imaging device within its Field of View whereupon the inspection captures multiple images of the illuminated top side of the sealed blister package using the said image pickup devise. The images then undergo analysis to determine the gray scale values of the sealing area. By comparing the gray level values with predetermined gray level values that are programmed at setup, a decision is made to reject the inspected item if the analyzed gray level values is not substantially the same as the predetermined gray level values, or to accept the inspected item if the analyzed gray level values is substantially the same as the predetermined gray level values or rejecting the blister if determined otherwise.
