Claim 0:
1. A system to evaluate an objective of an endoscope, the system comprising:
an objective from an endoscope, the objective being apart from the endoscope and having an optical axis;
an image capture system configured to capture a plurality of intermediate images of a formed image from the objective, the image capture system being movable along the optical axis to capture the plurality of intermediate images, and the formed image from the endoscopic objective having a curved focal plane and each intermediate image of the plurality of intermediate images corresponding to a different image plane with respect to the optical axis taken from the curved focal plane; and
an image processing system communicatively coupled to the image capture system to receive the plurality of intermediate images from the image capture system, the image processing system configured to extract at least one portion from each intermediate image of the plurality of intermediate images that corresponds to an in focus portion of the intermediate image, the image processing system configured to assemble the extracted portions from the plurality of intermediate images to form a final image, wherein the final image corresponds to the formed image from the objective, and wherein an evaluation of the final image by the image processing system determines acceptability of the objective,
wherein the image capture system includes at least one optical component configured for relaying and focusing the formed image and curved focal plane, and
wherein the image processing system is configured to reject the objective responsive to determining that the final image is not acceptable.
