This video demonstrates the trapping of a 1 µm to 3 µm particles as well as larger bodies such as starch grains by Thorlabs’ EDU-OT1(/M) Optical Tweezers Educational Kit. Optical tweezers, also known as optical traps, move and manipulate small particles using only a beam of light. A focused laser beam is used to exert forces on electrically uncharged particles with sizes from 1 to 10 µm, allowing the particles to be trapped, moved, and manipulated. This optical tweezers kit is optimized for classroom and lab use. It features an easy-to-construct optical path and sample positioning stage, a visible laser source, and a camera system for easy demonstration. The kit is assembled on a 30 cm x 60 cm (1′ x 2′) aluminum optical breadboard (included) and can be easily moved for demonstration purposes without needing realignment.
