dicam pro
This is a high performance intensified CCD camera system with gating times down to 1.5ns. With its 12bit dynamic range and a high resolution
CCD image sensor it features an excellent signal-to-noise-ratio and the
ability of single photon detection. The system is suited for applications in
environments with high electromagnetic disturbances. A high speed seri-
al fiber optic data link connects the system to the PC. The camera can be
triggered by light or electrical input.
