The acA2000-50gmNIR NIR-enhanced camera offers increased sensitivity in the NIR range. It achieves this through the use of a thicker substrate layer that is significantly simpler and more cost effective than previous CCD technology. It opens up an entirely new world of applications for projects that require good sensitivity in the near-infrared range, with wavelengths that must measure over 850 nm. This camera offers quantum efficiency of around 40% in the 850 nm range, or about twice the efficiency of non-NIR-optimized cameras.

The Basler ace provides a full set of features to address a wide range of applications. You may adjust the camera’s black level, gain, and area of interest. Up to eight areas of interest may be "stacked" and output as a single image. There is support for pixel binning, mirroring, test images and a luminance lookup table. Parameters may be sequenced for fast on-the-fly changes. The camera can automatically set gain and exposure, either once or continuously, based on the intensity of pixels in an image area of your choosing.

This camera is built on the CMOSIS CMV2000 NIR-enhanced progressive scan sensor having 2048 x 1088 pixel resolution. Customers love the 2:1 aspect ratio to image text and long narrow parts. The camera offers an amazing 60% quantum efficiency. Delivering 50 frames per second at full resolution, you can have both speed and resolution.

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.
