Lens Manufacturers: Do You Know The Best Test For Lens Performance?
 
By Kevin Urben, Image Science, Ltd.

A high-quality lens begins with a good design, tolerant to small manufacturing errors. Next, the manufacturing process must be tightly controlled, from the individual lens elements to the final assembly. However, since small errors in manufacturing can result in serious loss of performance, end-of-line testing is then necessary to identify lenses that fail to meet the desired quality requirements.
