USB interface compatible counting unit


The C13182-01 is a counting unit designed for high-speed light detection. A high-speed photon counter can be configured by combining this unit with a high-speed amplifier. This unit uses the double-counter method that has two counter circuits to allow measurements with no dead time.


Ideal for photon counting using a high-speed photodetector such as a Hybrid Photo-Detector (HPD)
Count linearity: more than 5 x 107 s-1
USB interface allows high-speed data transfer
Accurate measurement with no dead time (Double counter method)
Sample software bundled
