Introduction  

This equipment combines the historically important Michelson interferometer and the high resolution Fabry-Perot interferometer in one rigid and compact structure
Michelson interferometer is still an important instrument in today's physics laboratories and is used for observing the interference phenomena. Fabry-Perot interferometer is for observing multiple-beam interference and measuring the fine structure of spectrum
Measurements are precise in two modes of operation. Switching between the two modes of operation and aligning components is relatively simple.
This instrument is suitable for physics teaching in universities and colleges
