SGG-1 series phase method light speed measuring instrument

Guo (same)

SGG-1The series phase method light speed measuring instrument is suitable for measuring the speed of light in research institutes and physics laboratories of universities. Modulate the light intensity of the measured signal in the experimental device, measure the corresponding phase changes caused by the propagation distance of the light, and ultimately determine the speed of light. It can also be extended to measure the refractive index of media such as organic glass, artificial crystal, anhydrous ethanol, etc.

This series of experimental instruments is divided intoSGG-1A(Basic type),SGG-1B(Extended type),）,SGG-1C(* Type) Three different configurations, providing multiple choices.
