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.

This demonstration ray optics system uses a Laser Ray Box which has bright, well-defined rays because it uses lasers rather than an incandescent light source. The Laser Ray Box projects 5 parallel
laser beams onto any flat surface. It contains five 1mW diode lasers (wavelength 635 nm). The laser beams are spread out into clearly visible lines by cylindrical lens inside the box. The beam paths can be observed from a relatively long way in a dark
room.
White acrylic board with linear and circular scale is provided for display of lines of light and measurement of geometric components like focal length of lenses etc. All optical components are made of transparent acrylic material with one side
grounded.

The Malus Law helps to understand polarization properties of light. It can also be used to study the light intensity relation of polarizer-analyzer. This apparatus comprises of a diode laser (as a light source), a polarizer, an analyzer assembly and a pinhole photo detector with output measurement unit.
Malus law of polarization is verified by showing that the intensity of light passed through two polarizers depend on the square of cosine value of the angle between the two polarizer axis. Laser light is used in this experiment because it's wavelength is almost
completely extinguished by the crossed polarizers. The laser beam travelling through a polarizer is observed as a function of the orientation of the polarizer. With a second polarizer the relative
orientation of the polarizers is determined. The transmitted light is measured by a photo detector and the Malus Law can be verified.

The Brewster's Angle Apparatus is designed to study the Brewster's angle phenomenon and the polarization of reflected light. When light encounters a boundary between two media with
different refractive indices, some of it is reflected and other part is transmitted. The fraction that is reflected is described by the Fresnel equations, and is dependent upon the incoming light's polarization and angle of incidence.
When a light beam incident on a transparent material can be resolved into two light components i.e. parallel (P) and orthogonal (S) components. These components have different reflection
coefficients and Brewster found that at a particular angle of incidence β (called Brewster angle), reflection co-efficient of parallel component goes zero. At this angle, direction of reflected and transmitted beam is orthogonal to each other.

This experiment set up is used for study of basic optics operation in lab. This can also be used for various parameter measurements like focal length and magnification of lens etc. For focal length measuring an observation screen is set parallel to optical axis so that path of a parallel light beam can be observed on screen after passing through a collecting or dispersing lens. The focal length is
determined directly as distance between lens and focal point. Focal length can also be measured by using U-V method of measurement.
