The ace series of cameras offer fantastic value. The acA720-520uc is built on the Sony Pregius IMX287 1/2.9" sensor. With large 6.9 µm pixels and 70% quantum efficiency, it captures bright images even with with short exposures. Large pixels can also lead to improved depth of field.

This camera features Basler PGI. It includes 5 x 5 debayering, color anti-aliasing, denoising, and sharpening. The result is dramatically improved color images.

This 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.
