pco.dicam C8
8-channel intensified sCMOS camera
We developed the pco.dicam C8 camera system as the logical next step to increase the image sequence length of the field-proven pco.dicam C4.
The light of a single optical input is equally distributed to 8 image intensifiers, each with a 25 mm (optionally: 18 mm) diameter and 4 ns shortest gating. With zero ns interframing time this corresponds to a burst rate of 250,000,000 fps. All optical elements deployed for the beam splitting and guidance are adopted from the very successful pco.dicam C4 design.
Each image intensifier is read out by a dedicated tandem lens coupled 4.2 MPix sCMOS sensor with 16 bit dynamic. A maximum of 848 fps @ full 4.2 MPix resolution is available. This equals 6.8 GByte/s of sustained image data rate. To transmit this huge image data rate in real time, the pco.dicam C8 uses 8 optical CLHS ports (80G fiber).
