Product Overview
The HRPCS is a true single photon counting camera providing the ability to capture and integrate ultra-low-light images in real time.
The HRPCS is a parallel readout device capable of detecting multiple photons at the exactly the same time. It’s readout rate of 50 frames per second at full resolution, low dark count rate and 1.3 Mpix sensor provides high sensitivity over a wide dynamic range.
Bespoke versions are available with any of the wide range of Photek’s image intensifiers. Full systems can be provided with sensor cooling for ultra low noise, computer controlled sample stage, sample temperature control and light-tight enclosures.
