optical tweezer

English

optical tweezer (plural optical tweezers)

A scientific instrument that uses a highly focused laser beam to hold and move the microscopic or smaller objects such as atoms and droplets, in a manner similar to tweezers.
- 2003, L. Allen, ‎Stephen M. Barnett, ‎Miles J. Padgett, Optical Angular Momentum (page 240)
  This angular momentum has been transferred to macroscopic particles trapped in an optical tweezer causing them to rotate.
- 2006, Banafshe Larijani, ‎Colin A. Rosser, ‎Rudiger Woscholski, Chemical Biology: Techniques and Applications (page 207)
  In order to make calibrated measurements from single molecules two more items are required: (1) a four-quadrant photodiode position sensor (4QD) to accurately measure the position of the bead held in the optical tweezer (Figure 12.5); […]
