Polarimeter

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). SP4-1740
