APD Controller

Nanonics designs a stand-alone Avalanche Photo-Diode (APD) controller with an integrated stabilized power supply and a digital counter. This accessory converts APD pulses to an adjustable analog signal. 
The analog output can be fed into the auxiliary analog input found in most SPM controllers to allow true single-photon counting digital NSOM/SNOM measurements.
