Certain substances,sugar solutions for example,are subject to a phenomenon known as the rotation of polarization as a result
of optical activity.The polari-meters manufactured by A. Kruss Optronic GmbH
are measuring instruments which use polarizing filters to determine this rotation
with pinpoint accuracy. What exactly is polarization,When held
against the light,a basic polarizing filter simply looks grey.Yet if two such
filters are held in tandem,a position is revealed through which light cannot
pass.Both filters have their own plane of transmission for the so called
polarization of light,and in the above mentioned position these planes are
vertical to each other. Substances subject to optical activity can
rotate the polarization of light.If such a substance is positioned between two
polarizing filters,a certain amount of light is admitted through the filter
pair.The amount of light now becomes a measurement for the passage of light
through the substance,for the concentration of the substance,as well as for
certain constants specific to the substance. |
