If a bubble is formed in the cell and that bubble stays in the light path, then the
optical rotation reading will fluctuate significantly and becomes unstable. Thus
care must be taken to avoid bubbles in filling the cell. Some manufacturers
supply ...

Sugar: User's Guide To Sucrose
A standard pure sucrose solution is defined as 100°S and a pure water solution
as 0°S. The instrument used to measure optical rotation is called a polarimeter,
while one calibrated in degrees S is more properly called a saccharimeter.

The International Pharmacopoeia
The specific optical rotation of a solid is the angle of rotation measured as
specified in the monograph, and calculated with reference to a layer 100mm thick

Optical Activity and the Chiral Discriminations
Subsequently, Biot (1817) established an approximate inverse square law
between the angle of the optical rotation, a, and the wavelength of the radiation,
X, a = K/X2 (1.1) where K is a constant characteristic of the optically-active
substance, ...
