Holmarc's Apparatus Model HO-ED-D-02A is meant for the study of diffraction patterns of single slits and to confirm Heisenberga s uncertainty principle. Here, the diffraction pattern is closely studied using a detector mounted on a translation stage. The instrument consists of 1.2 meters long optical rail along with carriages and opto-mechanics. At one end of the rail, X-translation stage with detector is mounted and at the other end, laser is held on a kinematic mount. Linear scale attached to the rail makes length measurements easy and convenient.

Experiment
To observe the diffraction pattern and calculate the slit width
To calculate the uncertainty of momentum from the diffraction patterns of single slits of differing widths and to confirm Heisenberga s uncertainty principle.
