NEW: Long-lasting LED illumination unit
The Small Universal Polarimeter is a visual circle polarimeter suitable for school and education. The 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 long lasting illumination unit (life time approx. 50.000 hours).
- The halogen lamp is less expensive and has a longer life time than spectral lamp. LED as well as are ready for use immediately upon switching 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.
