Small Universal Polarimeter
The Small Universal Polarimeter is a visual circle polarimeter suitable education and teaching laboratories. This polarimeter has a circular scale of ±180° angular degrees divided into full degrees. Together with the Vernier scale, rotations can be measured to an accuracy of 0.1° and with a little practice they can be estimated to an accuracy of 0.05°.
There are three possible lighting units:
- The LED unit is a very robust and long lasting illumination unit (life time approx. 50.000 hours
- The halogen lamp has a longer life time than spectral lamp. Like the LED, they are ready for use immediately after switching them on
- The spectral lamp unit is recommended for higher absolute accuracy
A sodium spectral lamp emits light of a defined wavelength (line spectrum). In order to block out undesired side spectral lines, coloured glass filter should be used. It also must be inserted into the light admission opening.
