Description

Mach-Zehnder interferometer is a common two beam interface optical interferometer. In a Mach-Zehnder interferometer a beam splitter is divides a coherent beam into two parts. These beams are deflected by mirrors and finally recombine by using another beam splitter. The interference patterns are formed when two beams with fixed phase relationship superimposed with each other. As beams are not reflected into each other but travel separate paths experiments with Mach-Zehnder interferometer is more effective than Michelson interferometer.

Experiment Performed

• To determine wavelength of laser light.
• To find refractive index of a transparent plate.
• To study refractive index change in air under different pressures and determination of refractive index of air.

Feature

• Precision kinematic mounts for optical components
• Optics used for design have very good surface quality
• Assembly of setup is very easy
