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.

Enlitech
Enli Tech provides the most advanced optical and non-destructive inspection technology, which can de-convolute the digital images back to the analog properties, such as quantum efficiency, spectral response, system gain K, Dynamic Range (DR), PRNU, DRNU, Linearity Error LE, and Chief-Ray-Angle (CRA). The testing solution can be applied to CCD and CMOS image sensors in aerospace, defense, and scientific camera field. Image sensor packages that can be tested by Enli Tech’s systems include bare wafers, dies, chips, or camera modules. Our image sensor testers can help users reduce the sensor-modules or camera-modules development time and RD budget.The SG-A system is the world’s first commercial CMOS Image sensor tester.
