2048 x 1536 images at 120 frames per second
Excellent quantum efficiency, dynamic range, SNR
PGI image enhancement

The ace series of cameras offer fantastic value. The acA2040-120uc is built on the Sony Pregius IMX252 1/1.8" sensor. It offers 3.2 MP (2048 x 1536) resolution with astounding image quality: high quantum efficiency, wide dynamic range, and extremely low noise.

When this camera is configured to use the sensor's full resolution, it can deliver 120 frames/second ("fps") over the USB3 interface. However, when configured to use less resolution, the frame rate will increase. As examples, 2048 x 1080 delivers 170.4 fps, and 2048 x 640 delivers 287.2 fps. (Note maximum frame rate also depends on output format, exposure time, and USB hardware.)

This camera features Basler PGI in-camera image optimization, including 5x5 debayering and color anti-aliasing for improved sharpness and reduced noise.

The camera has a global shutter for “stop-action” imaging. The camera can output a flash window signal to control the light source.

With USB3 Vision, a single cable is used to apply camera power and to transfer data between this camera and a PC, keeping cable runs to a minimum. An auxiliary connector is provided for terminating the input and output signals – there is a total of four.

The Basler ace provides a full set of features to address a wide range of applications. Pixel data can be output in 8 or 12 bit depth. You may adjust the camera’s black level, gain, area of interest, input debounce, and trigger delay. It features automatic exposure control, pixel binning, horizontal image mirroring, event reporting, sending of test images, and a programmable lookup table. There are also “chunk” features that include a frame counter, time stamp, trigger input counter, and CRC checksum calculator. Note that not all features may be available when using third-party software.

Because this camera is USB3 Vision and GenICam compliant, there are many third party software applications and API’s that are compatible. Basler offers their royalty-free Pylon SDK for 32 and 64 bit Windows and Linux platforms.
