White light metrology and other applications for high full capacity camera with CMOSIS CSI2100 image sensor

Accurately measure low contrast structures in bright scenes at high speeds 

We are exploring white light interferometry applications for our extreme high full, high speed camera, such as (non-destructive) interferometric optical microscopy, defraction based contrast imaging, 2D shot noise limited bright scene imaging, and more. Adimec developed this camera for non-invasive optical imaging for cancer assessment as part of the CAReIOCA consortium.

The new 2 Megapixel CoaXPress camera (Q-2A750-CXP) brings a 1440x1440 resolution at up to 720 fps based on 12 micron pixels. The design of the pixels in this global shutter CMOS image sensor (CMOSIS CSI2100) is optimized for maximum full well performance. An industry unique full well capacity (FWC) of over 2 million electrons per pixel is between 100 to 200 times higher compared to commonly available high speed CMOS sensor technology today (reference: 10-20 kel full well). 2 million electrons full well capacity per pixel results in extremely good shot noise performance of up to 63 dB SNR, making it possible to accurately detect very weak contrast variations in bright environments at high throughput. This camera is ideal for inline optical metrology systems and real-time applications.

 

Adimec offers the camera in a low power, compact outline design, not requiring forced cooling through a fan. This provides optimal design freedom for integrating optics and placement in inspection tools and microscopes.
