Optical tweezers are able to trap and manipulate small particles using a focused laser beam to exert forces on electrically uncharged particles. This video show the trapping and manipulation of 1 µm and 3 µm particles. These particles can be trapped, moved around the slide, released (via defocusing), etc. The optical tweezers kit can manipulate particles up to 10 µm in diameter and demonstrated in the video by trapping larger starch grains and fat droplets. 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.
