Laurent’s half shade polarimeter

Item Code: SK018

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.
... [α]^T_λ = α/l.c
[α]^T_λ = specific rotation
λ = wavelength of light
T = temperature
α = observed rotation in degrees
l = cell path in decimeters
c = concentration (gm/100ml)
