1000882 Includes Only:1 Control unit with a transmitter, receiver and integrated power supply unit1 Fresnel lense on shaft1 Triple-prism reflector on shaft3 HF cables, 1 mAdditionally required:Optical BenchOptical Rider (2x)Stand EquipmentEquipment set for determining the speed of light thanks to electronic run-time measurement. Comprises a compact housing containing a transmitter emitting short LED pulses, a photo receiver and a calibrated, oscillating quartz generator producing chronologically precise square-wave pulses. Emitted light pulses are returned by an internal reflector and by a triple-prism reflector placed a long distance from the light source. The returning light signals are then superimposed on the original signal. A dual-channel oscilloscope is used to measure the time difference between the two signals. The speed of light can be calculated from this difference and the distance to the triple-prism reflector.
