Description

Polarimetry is a rewarding
field of study in any Post-
16 course to explore the
applications of polarised
light.
This student polarimeter
uses a monochromatic
yellow LED light source and
simplified construction to
make the topic available for
study in any laboratory. A 10cm long specimen
tube contains the sugar solution under test and
this is placed in the body of the apparatus above
the polariser and light source.
The lid contains the second polariser and has a
scale on the outer edge so that as it is rotated the
position for extinction can be found for different
solution concentrations and the angle of rotation
recorded.
Full instructions included with everything
supplied except the d.c. power supply ( up to 10V).
