Polarimeter with a lighting unit comprising four monochromatic LEDs for determining the angle and direction of rotation of polarised light as a function of wavelength as well as sample thickness and concentration with the help of an optically active substance.
The light emerging from those LEDs that are lit is polarised linearly and transmitted through a fitted sample cylinder filled with the optically active substance. The analyser in the cover is used to identify the direction of polarisation which can be read on the cover’s angle scale.
Wavelength of LEDs: 525 nm (green), 580 nm (yellow), 468 nm (blue), 630 nm (red)
Dimensions: approx. 110x190x320 mm³
Weight: approx. 1 kg
Voltage range: 100 - 240 V, 50/60 Hz
