The ace series of USB3 Vision cameras offer fantastic value. The acA1920-155um is built on the Sony Pregius IMX174 1/1.2" sensor. It offers 2.3 MP (1920 x 1200) resolution with astounding image quality: high quantum efficiency, wide dynamic range, and extremely low noise. Delivering up to 164 frames per second at full resolution, this USB3 camera is even smaller than Basler's GigE models.

This camera has relatively large 5.86 µm pixels. This enables greater light sensitivity, greater depth of field, and demands less performance from a lens. If configured to use its full resolution, it has an image circle of 13.27 mm and a 1" lens is needed. To instead use a lower cost 2/3" lens, simply configure the camera for less resolution. All the following resolutions can use a 2/3" (11 mm) lens: 1500 x 1126, 1200 x 1200, 1634 x 920, 1440 x 1200. These resolutions can deliver frame rates of 176, 166, 214 and 166 fps, respectively.

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.
