In this research, the experimental and theoretical studies to measure the wavelength of laser light by Mach–
Zehnder interferometer were conducted. Then, the results were compared with Zemax software. The fringes have been
obtained both as shining and dark. The wavelength of laser light and the diameter of fringes were calculated by the optical
system. The calculation relies on the measure of the airy disk diameter, whose approximation is directly proportional to the
wavelength of the laser source; and to the space between the aperture and the image plane. However, the calculation is
reciprocally proportional to the diameter of the aperture. Then, the results were compared with Zemax software, where the
ratio of error is very small.
