Targets high-throughput manufacturing and optical inspection

ams recently launched the CSG14k, a global
shutter image sensor that delivers greater image quality and higher throughput
than existing devices that support the 1-inch optical format, according to the
company. The new image sensor targets automated
optical inspection (AOI) equipment and machine-vision applications.

The CSG14k
features a 3,840 × 3,584-pixel array, providing 14-MP resolution at a greater
frame rate than competing devices. The sensor’s 3.2 µm × 3.2-µm pixels are 66% smaller than the previous generation of ams’ 10-bit image sensors,
enabling it to provide better performance and higher resolution while offering
a 12-bit output and lower noise.

The higher
speed and image quality are advantages in high-throughput production settings,
said the company, by enabling machine-vision equipment to take more detailed
and more accurate images of objects as they travel along the production line at
high rates of speed. The new sensor is also a good fit for AOI equipment, sorting
equipment, laser triangulation, and other measurement instruments and robotics.

“Future
advances in factory automation technology are going to push today’s machine-vision
equipment beyond the limits of its capabilities,” according to Tom Walschap, ams marketing director in the CMOS Image Sensors business line. “The breakthrough in image
quality and performance offered by the CSG14k gives manufacturers of machine-vision
systems headroom to support new, higher-throughput rates while delivering
valuable improvements in image quality and resolution.”

The CSG14k
features a 12-bit output that delivers enough dynamic range to handle a variety
of subjects and lighting conditions, and its global shutter featuring true
correlated double sampling (CDS) provides high-quality images of objects moving
rapidly while eliminating motion artifacts.

The new sensor’s
configuration settings can be tuned to meet a specific application’s
requirements. Configuration options include low-power modes at a reduced frame
rate and optimizations for low noise and high dynamic range.

The CSG14k comes
in a 218-pin, 22 × 20 × 3-mm LGA package that’s compatible with 1-inch lenses
commonly found in small-form-factor camera designs and includes a sub-LVDS
output interface compatible with existing CMV image sensors from ams. The new device will be available for sampling
in the first half of 2019.
