GigE interface
376 full frames per second
Compact 42 x 29 x 29 mm housing
1/4" CMOS sensor with Global shutter

The ace series of GigE Vision cameras offer fantastic value for very challenging applications (e.g. microscopy, medical technology, transport technology). The acA640-300gc contains a PYTHON 300 CMOS sensor from ON Semiconductor. The 1/4" sensor contains 640 x 480 pixels, and delivers up to 376 frames per second, at full resolution, all in a compact 42 x 29 x 29 mm housing.

Because the Basler ace GigE camera uses the same 29 x 29 mm footprint that has been standard on analog cameras for many years, replacement of analog cameras is easy. Some existing Camera Link cameras and IEEE 1394a or 1394b cameras with this same footprint can also be easily replaced.

Using a Power over Ethernet (“PoE”) configuration, a single cable may be 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 signal – there is one of each. The input may be configured to trigger image acquisition, reset the frame counter, or reset the software trigger count. The output may be configured to indicate acquisition trigger wait, exposure active, flash window, or timer active. Or the output may be controlled via a PC. The auxiliary connector may be used to power the camera if PoE is not available.

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 GigE 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.
