Laboratory Equipment
Leading Manufacturer of franck hertz experiment apparatus, goniometer based apparatus for diffraction instrument, single slit diffraction and heisenbergs uncertainty principle and xrf spectrometers from Chennai.Franck Hertz Experiment Apparatus
The Franck - Hertz Apparatus (Model No: HO-ED-EM-04) is designed for verifying the existence of quantized states. The instrument can, not only lead to a plot of the amplitude spectrum curve by means of point by point measurement, but also directly display the amplitude spectrum curve on the oscilloscope screen.
The Franck-Hertz experiment is a fundamental quantum physics experiment which confirmed the quantization of atomic energy levels. This experiment supports Bohr model of atom. Apparatus used for the experiment consist of a tube containing low pressure gas, fitted with four electrodes.

Single Slit Diffraction and Heisenbergs uncertainty principle
Holmarc's Apparatus Model HO-ED-D-02A is meant for the study of diffraction patterns of single slits and to confirm Heisenberg’s uncertainty principle. Here, the diffraction pattern is closely studied using a detector mounted on a translation stage. The device 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.
