Case study: Renishaw incremental encoders enhance the stability and efficiency of lens testing (pdf)

Smartphone cameras have become indispensable tools. People are now accustomed to them as part of daily life – shooting and then sharing with friends and family. Lens quality is more important now than ever, due to the ever-increasing number of megapixels found in today’s digital phone cameras. Frequently, the resolution of digital photos is actually limited by the camera’s lens - and not by the resolution of the detector itself. Major smartphone manufacturers are now in a race to enhance their camera capabilities in order to attract new customers. Taiwan’s UMA Technology Inc (UMA) develops optical testing equipment for industry to provide accurate, rapid and reliable lens error detection schemes.
