• Mach-Zehnder interferometers use optical path difference between optical paths L1 and L2 in the figure.

• With  the same lengths of L1 and L2 and a transparent sample (solid, liquid,  or gas) placed in one optical path, an interference fringe moves in  proportion to the extent of the change in the refractive index.

• Consisting  of mutually independent mirror and beam splitter units that enable  broad layout flexibility, Mach-Zehnder interferometers can be used to  measure larger samples.
