Kerr Effect

Understand the Kerr effect like you never have before!

• Demonstrate the Kerr effect in nitrobenzene solution
• Measure the light intensity using photo detector

This apparatus is used to demonstrate the Kerr effect in nitrobenzene solution and to measure the light intensity as a function of voltage across the Kerr cell using photo detector.

Salient features:
All connections are made using safety sockets.

Principle and Working:
In the present setup, a small glass container mounted with plate capacitor is filled with liquid. The container is kept between two filters placed at 90°. There will be dark field of view on screen initially but after applying electric field, the field of view brightens, because the light beam becomes elliptically polarized when passed through the birefringent liquid.
