Optical tweezers Tweez250 by Aresis – Capture particles, set traps

The optical tweezer Tweez250 boasts a compact design combined with highest precision and accuracy. Its core is a powerful, extremely stable laser that is diverted and controlled by acousto-optic deflectors. With this technology, 2500 traps can be generated at a frequency of 100 kHz. This means that each trap is subject to quasi-stationary conditions, Tweez250 can capture several particles, which allows measurements of the forces between two micro structures by a precise control of the traps.

Optical tweezers use forces created by radiation pressure caused by a highly focused laser beam.


  • Capture particles
  • Force measurements on molecular interactions
  • Microrheology
  • Manipulation of small particles
