A404K A400 Area Scan Series Basler

The A400 series was developed with the goal of offering a high performance camera to meet the most stringent requirements in terms of resolution, speed, and image quality. This goal was realized by using a sophisticated four megapixel sensor and a unique camera backend, a combination which provides brilliant image quality and the possibility of fast preprocessing. To ensure reliable, consistent quality, A400 variants are 100% quality checked and calibrated. All of this makes A400 cameras exceptionally flexible and reliable tools for many applications

All A400 cameras contain a high quality CMOS sensor with 2352 x 1726 active pixels. While the speeds of the most common CCD sensors are limited to 15 fps, A400 variants offer superior maximum
frame rates:
• A402k/kc – 24 fps at full resolution
• A403k/kc – 48 fps at full resolution
• A404k/kc – 96 fps at full resolution
• A405k/kc – 167 fps at 2320 x 1726
• A406k/kc – 209 fps at 2320 x 1726
The A400 family sets a new standard of excellence with performance and image quality that rivals CCD cameras. The extraordinary image quality results from the use of advanced CMOS sensors and sophisticated electronic design. And three different image enhancement features can improve image quality even more:
• Column shading correction to eliminate fixed pattern noise
• DSNU shading correction to eliminate dark signal non-uniformity
• PRNU shading correction to eliminate photo response non-uniformity
The absence of blooming or smear represents another advantage over cameras with CCD sensors. Missing codes are not an issue for the A400 and the images are very homogeneous in this respect. The fast FPGA used in A400 cameras enables the option of onboard preprocessing and allows the implementation of individual algorithms adapted to customer requirements.

When the area of interest (AOI) feature on an A400 camera is used, only a designated portion of the image will be transmitted out of the camera. This reduces the amount of data transmitted by the camera and increases the maximum allowed frame rate. On A400 cameras, a set of individual AOIs can be defined in an AOI list. Each individual AOI can have different parameter settings such as AOI position, AOI dimensions, exposure time, and flash activation.

The resulting sets of AOI parameters can be saved in the camera and executed internally. This means that the slow serial communication port is not needed to change from one set of AOI parameters to another and this allows higher frame rates during operation. The AOI editor software tool makes creating an AOI list simple. With this easy-to-use tool, each AOI in the list is created in a graphical way by using a captured image to position the AOI in the most interesting region and to adjust its size. The AOI list is automatically created, and it gives an overview of the positions, sizes, exposure times, delay times, and flash activation for each AOI in the list. The program highlights any incorrect settings and provides the information needed to make corrections.
