Device for photon counting system

[hanh]

Hi

I want  to design a photon counter for my optical measurement (very low intesnity). I need experiences of design and advice to choose a suitable  counter : low rate to high rate (up to 100M counts /sec), little dead time..., TLL input. I was told about such a PCI counter card.

Thanks

Hi hanh,

The PCI counter/timer board that matches the specifications you have given would be the PCI-6602. You can find more detail about it in the NI 660x Specifications. The 100 counts/sec would be possible but you will have to use the prescaler. Take a look at this device and see if it matches what you need.
