The included adapters allow 55 mm of distance from the adapter to the imaging sensor, and a spacer is needed if the camera has less backfocus.
The fan can be powered by any 12V DC power supply that provides at least 100mA and has a 5.5 mm/2.1 mm tip positive DC power plug.
It takes about 30 turns of the focusing knob to go through the entire range of focus.
