Introduction to UP1 Polarimeter
The UP is a half shadow polarimeter. It has a circular scale of +/- 180 degrees
marked in 1 degree increments together with a vernier scale giving accuracy of
0.1 degrees or even 0.05 degrees for a practiced operator. The analyzer is
adjusted by rotating the vernier scale and comparing the half shadows from the
polarizer and analyzer. The vernier scale has large diameter which makes it
easy to make small adjustment in angle to obtain an accurate reading. The
scale, polarizer and analyzer are tilted to make the viewing position
comfortable for the operator. |

Principle of Operation
Polarizing filters are used for the polarizer and analyzer. The polarizer is
fitted with a thin two piece quartz disc which produces a divided field of
view, the half shadow angle of which is depended on the light source being
used. With a sodium lamp ( wavelength 589 nm ) it is 8 degs. and with mercury
lamp ( wavelength 546 nm) it is 9.5 degs. The UP1 can be used with a halogen
lamp and interference filter to define the wavelength or with a spectral lamp (
sodium, mercury etc. )
