Laurent’s Half Shade Polarimeter

Polarimeter measure the rotation of polarized light as it passes through an optically active substance and the tendency of the molecule to rotate the plane polarized light towards clock-wise or anti-clock wise direction whose extent of the rotation can be measured.

Features:

• Polarimeter function can be carried out precisely in an economical unit.
• Sturdy metal housing and modular construction.
• Sodium source can be used in vertical & horizontal positions
• Modern and user friendly design.
• Least count 1°

Objectives:

• To study the principle of operation of a Half-shape polarimeter.
