Products Sensors
GMAX3265 65MP sensor Gpixel has released the GMAX3265, a 65-megapixel image sensor with low-noise 3.2µm charge domain global shutter pixel architecture. Ximea and Adimec have both built cameras based on the sensor. The sensor offers 9,344 (H) x 7,000 (V) charge global shutter pixels with a read noise of less than 2e-, 70dB dynamic range, and 1e-/p/s dark current at room temperature. Thanks to the light pipe technology, the sensor exhibits excellent shutter efficiency of 1/30,000 and large angular response.
Consisting of 56 pairs sub-LVDS data output channel and each running at a maximum of 1.08Gb/s, the GMAX3265 delivers 85fps at 10-bit output or 53fps at 12-bit output. The high resolution and fast frame rate increases the system throughput for industrial inspection applications, such as semiconductor, PCB or AOI. The sensor is designed with an on-chip
sequencer supporting various exposure and region-of-interest modes.
Gpixel has also expanded its Gmax product family with two 2.5µm global shutter sensors designed for C-mount cameras. The GMAX2505 is a five-megapixel, 1/2-inch sensor, while the GMAX2509 is a nine-megapixel, 2/3-inch sensor.

Cameras
CSG14k image sensor Ams has released a global shutter image sensor for machine vision and automated optical inspection equipment. The CSG14k sensor supports the one-inch optical format. It features a 3,840 x 3,584 pixel array, giving 14-megapixel resolution. The CSG14k’s 12- bit output provides sufficient dynamic range to handle wide variations in lighting conditions and subjects. The sensor’s global shutter with true correlated double sampling produces high-quality images
Fifty megapixel CCD
On Semiconductor has introduced a 50-megapixel CCD image sensor. The CCD provides the detail and uniformity needed for inspection of smartphone displays, as well as circuit board and mechanical assembly inspection, and aerial surveillance.
The KAI-50140 is designed in a 2.18-to-1 aspect ratio to match the format of modern smartphones, reducing the number of image captures required to inspect a full display. The 4.5µm interline transfer CCD pixel provides high resolution with a true electronic global shutter, while preserving critical imaging performance. The device supports frame rates up to 4fps through the use of flexible 1, 2, or 4 output readout architecture.

of fast-moving objects free of motion artefacts.
The 3.2 x 3.2µm pixels are 66 per cent smaller than the pixel in the previous generation of 10-bit Ams image sensors, while offering a 12-bit output and lower noise.
The image quality and speed of the CSG14k provide advantages in high-throughput production settings, allowing machine vision equipment to take a more detailed and accurate picture of objects moving along the production line at high speed. The
sensor is suitable for use in applications such as automated optical inspection, sorting equipment, and laser triangulation.
Configuration options include low-power modes at reduced frame rate, and optimisations for low noise and high dynamic range. The device has a sub-LVDS output interface.
It is housed in a 218-pin, 22 x 20 x 3mm LGA package which is compatible with one- inch lenses.

Zivid One Plus models Norwegian 3D machine vision camera company, Zivid, has introduced three full colour 3D cameras. For detailed inspection and verification of very small objects, typically presented in trays or open containers, the Zivid One Plus S camera operates over a focal distance of 0.3m to 1m, and provides a maximum field of view of 650 x 480mm. The camera’s spatial resolution is 0.12mm, with a depth precision of 0.03mm, at 0.3m. The Zivid One Plus M works optimally from 0.6m to 2.0m. The medium range camera has a maximum field of view of 1,370 x 900mm, with a spatial resolution of 0.23mm and 0.07mm depth precision at 0.6m. Zivid One Plus M is aimed at picking small- to medium- sized objects carried in standard totes or bins. For picking, handling and depalletising of larger objects, the Zivid One Plus L has a large field of view of 2,110 x 1,360mm at a maximum operating distance of 3m. It handles standard Euro Pallet applications carrying a mixed load of boxes, totes and free-standing objects.
Using a principle of time-coded structured light projection, the cameras capture 3D, colour and quality data on a single sensor chip. They operate at an acquisition rate of up to 13Hz.

Ricoh SC-10 camera
The Ricoh SC-10 camera inspection system is designed to both provide assembly instructions to operators and verify each step has been completed correctly. The simple, self-contained camera system, which is used in many different manufacturing environments in Japan, is now available in Europe from Stemmer Imaging. A set of work instructions are loaded into the camera and displayed on a monitor, while the camera scans the work piece. The human operator follows the on-screen assembly instructions and after every action, the system compares the result to the correct stored image before the next step can be taken. This reduces errors. The Ricoh SC-10 series automatically checks the assembly status and identifies incorrect or missing items by using either pattern matching, colour verification or identifying the presence of textures. In addition, when used in conjunction with a barcode scanner it can record the part number and select the job instruction set, record the serial number and user ID. Each step completed is recorded in a CSV file, including the time spent and an optional image of the inspection can be saved. This means that it can be used for assembly work analysis and traceability.
