Very short but powerful pulses of light are emitted from the box. When the light pulses hit the special retroflective foil of the reflector they are directed back towards the source  with no need for tedious adjustments. Via a beamsplitter, the light pulses finally hit a high speed photodiode, converting them into electric pulses to be displayed on an oscilloscope. A separate synchronization signal marks the time of pulse emission and constitutes a reference
for timing the pulses.

Included are:

Speed of light apparatus
Power adapter
Reflector screen
English manual
The oscilloscope is not included.


An economy class, two channel, 25 MHz oscilloscope is usually OK, but better results are obtained with a 50 MHz or 100 MHz oscilloscope.
