The ace series of cameras offer fantastic value. This model 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 171.8 fps, and 2048 x 640 delivers 287.2 fps. (Note maximum frame rate also depends on output format, exposure time, and USB hardware.)

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.

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

Because this camera is USB3 Vision and GenICam complaint, 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, Linux and OS X platforms.
