Low-Cost 3D-Printed Polarimeter
Paweł Bernard, James D. Mendez
Abstract
3D printing and simple electronics were used to create a polarimeter suitable for a variety of chemistry courses. This device allows instructors to demonstrate optical activity but is also easy to use and low cost enough to be widely available for student use, as well. The instrument uses an LED light source and detector housed in a 3D-printed base. By rotating the top piece, users can visually detect changes in brightness or measure this directly with a multimeter.
