High sensitivity time delay integration TDI mode

The HNü TDI camera provides exactly what is to be expected from a high-end CCD TDI camera: virtually no noise. The TDI readout mode allows for a longer exposition period positively impacting the image quality. Integrating the patented CCD Controller for Counting Photons, it creates fewer clock-induced charges than other CCD cameras. In short, it is the finest camera for demanding scanning applications.

The HNü innovative packaging ensures optimal chip operations at -85 °C with air cooling

Time-Delay Integration TDI Principles

A readout mode based on the concept of the accumulation of cumulative exposures of the same object as it is moving linearly under the detector. It synchronizes the transfer of the charges from one line to the next with the same speed as the object is moving under the camera:

 Highest quantum efficiency

In order to detect the most photons, CCD cameras must optimize the total effective quantum efficiency (QE). In turn, this critical parameter is influenced by the sensor’s quantum efficiency.
