Adimec has introduced the new 25 megapixel Sapphire Quad CoaXPress high-speed area scan camera, the S-25A70/CXP. Currently with a select group of customers for field testing and evaluation, the camera is the latest addition to the company’s global shutter CMOS metrology camera portfolio.

The reliable and high image quality enables measurement of ever smaller critical structures or defects with the increased accuracy and throughput required by in-line optical metrology systems. The S-25A70/CXP camera uses the On Semiconductor Vita25k global shutter image sensor and delivers images of 5,120 x 5,120 pixels at a maximum 73 full frames per second.

The camera is equipped with the CoaXPress v1.1 Quad interface (4 x CXP-6) using Adimec’s new 2 gigapixels/s camera platform. The new camera architecture was designed specifically for high data rate imaging with the low power, fanless Quad CoaXPress implementation in a compact form factor. The S-25A70 is therefore easy to integrate without unwanted noise caused by heat.

The Sapphire series contains a defect pixel correction algorithm especially designed for large area scan image sensors. According to the company, this algorithm maintains high image uniformity even with a high number of defect pixels that are more common in these kinds of sensors. The S-25A70 is designed to be stable and provides reliable and predicable high quality images required for large field-of-view inspection equipment, such as in semiconductor and electronics manufacturing, FPD and profilometry.

CoaXPress CXP-6 Quad (4 x CXP-6) offers a peak transfer rate of 2 Gigapixels/s with data transmission between the camera and frame grabber at up to 25Gb/s (4 x 6.25Gb/s). The low power consumption of the camera is also enabled over just one CoaXPress interface cable. At maximum speed, cable lengths of more than 30 metres are supported without the need for signal repeaters.

This camera series will be available in production in the second half of 2015.

Adimec has also released a 2 megapixel CoaXPress camera (Q-2A750-CXP), which offers 1,440 x 1,440 resolution at up to 720fps based on 12µm pixels. Adimec developed this camera for non-invasive optical imaging for cancer assessment as part of the FP7-funded CAReIOCA consortium.
