Product Description
DIODE LASER DIFFRACTION EXPERIMENT

Experiment
Exp-1 Diffraction of light by single slit.
Exp-2 Diffraction of light by double slit.
Exp-3 Diffraction of light by multiple slit.
Exp-4 Diffraction of light by fine wire.
Exp-5 Diffraction of light by cross wire.
Exp-6 Diffraction of light by wire mesh.
Exp-7 Diffraction of light by transmission grating.
Exp-8 Diffraction of light by coarse grating.
Exp-9 Diffraction of light by circular aperture (Pinhole).

Working :
Diffraction phenomenon of light can be observed when a laser beam passes through a diffraction slit. The intensity pattern can be determined using a pin photo detector with fine movement across the diffraction pattern.
In the present setup, the light intensity in the terms of current or voltage is noted at closed intervals by finely traversing the detector movement and observing the light intensity on a digital multimeter. The intensity versus distance curve is plotted on a graph for calculations. The device consists of one meter long optical bench with two transverse saddle for laser and slit mount and one transverse saddle with micrometer for detector. A number of diffraction slits and gratings are provided with this setup.
