Building a 2-photon microscope -- 2

PMT high voltage power-supply: Using Hamamatsu C4900-1 in combination with 12V powersuply (Power One) is a cost efficient solution. For controlling voltage, one needs a potentiometer (50 ohm).(~$0.2K each).

XYZ-motorized control: I use XY-stage from NEAT (XYR-4040), and Z-axis from Oriental motor (PK266-02A) coupled to microscope focus control. Cables are connected to Sutter MP285. Originally MP285 is for electrode manipulator, but one can ask for modification for the NEAT stage (KS3.4). $7K.
