CMOS Image Sensor Tester


Quick Installation and Rapid Deployment Can Help You Speed Up Time to Market.

  The SG-A system is the world’s first commercial CMOS Image sensor tester. SG-A can provide the most comprehensive CMOS image sensor parameter characterizations, such as full-spectrum quantum efficiency QE, overall system gain K, temporal dark noise, signal-to-noise ratio, absolute sensitivity threshold, saturation capacity, dynamic range, DSNU, PRNU, Linearity error, and chief-ray angle CRA.

   The device under test can be several type of CMOS image sensor modules. The inspection procedures are complied with the EMVA 1288 standard. Therefore, SG-A CMOS image sensor tester can be used to do wafer-level optics inspection, processing parameters controlling, micro-lens design, micro-lens verification. The highly collimated beam (< 1°) of the SG-A CMOS image sensor tester can overcome the inspection difficulties of new manufacturing processes that traditional optical systems (such as integrating sphere systems) cannot solve. The processes include small pixel   (< 1 um), BSI and 3D stacking, micro lens, new Bayer array design, and so on.
