The cameras under test were the uEye® model UI-1220-M, a monochrome camera with a 1/3“ CMOS sensor and a resolution of 752 x 480 pixels, and the UI-2220-M, a monochrome camera with a 1/2“ CCD sensor and a 768 x 576 pixel resolution.
With an excess housing temperature of only 3 °C and 4 °C, respectively, the cameras shine with measurement values that are among the lowest achieved so far. Both models have also proved that the design as well as the optical density inside the
C-mount lens connector, which effectively eliminates stray light in the flange, are exemplary and the dark noise is very low.
The test defined by EMVA 1288 ensures that the performance data of cameras and image sensors are transparent and easy to compare. The standard is an initiative launched by the European Machine Vision Association (EMVA) to provide users with greater transparency in view of the growing variety of sensors and the increasing functionality of cameras.
The two cameras tested were from IDS's standard uEye® series which covers a very wide area of applications. The range features different monochrome and color cameras with CCD or CMOS sensors, rolling or global shutters and, optionally, with an internal memory. The resolution ranges from 640 x 480 pixels to 2560 x 1920 pixels, i.e. 5 megapixels.
