AP-852-A

Polarimeter research 200mm / 400mm tube with half shade vernier scale slow motion Abron with sodium lamp set

An improved optical system with half shadow system. Permanent focus i.e. to say, once the dividing line is focused to suit the eye, this focus is never disturbed by inserting tubes of sugar or other solutions, regardless of the fact that they may not be completely homogeneous, or of the length of the tube.

• Scale : Angular 0-360° subdivided 1° Micrometer drum
• direct reading to 0 - 5° and by estimation 0 - 2°.
• Sugar : - 30 to +120 ISS, Micrometer drum
• enables reading to 0 - 1 sugar degree directly
• 0 - 5 sugar degree by estimation.
• Telescope magnification: 5x.
• Range of measurement: + 10° to  + 110°.
