Use this CCD Linear Camera to investigate optical phenomena in real time. Adjust sensitivity depending on the intensity of the light source, several measurement and signal processing functions – includes camera, neutral gray filter, user-friendly software, patch cords & transport case. Experiment topics to explore with the Interferometer include: Michelson interferometer, Fabry-Perot interferometer, determine the refractive index of glass and air, and Twyman-Green test for optical components (qualitative). Polarimeters measure the rotation and the rotation direction of the polarization plane of polarized light through optically active substances as well as determine the concentration of liquids. For large audiences, use the Demonstration Polarimeter on a overhead projector   «««
