Abstract
Beam manipulation member for use in an optical tweezers system, the beam manipulation member comprising at least one optical element, being controllably deformable in order to act on a laser beam in response to signals coming from the optical tweezers system. The beam manipulation member may be used to change the focal distance of the optical tweezers system and also to deflect the laser beam.

Beam manipulation member for use in an optical tweezers system, the beam manipulation member comprising at least one optical element, being controllably deformable in order to act on a laser beam in response to signals coming from the optical tweezers system.
Beam manipulation member for use in an optical tweezers system, the beam manipulation member comprising at least one optical element comprising material having a controllable refractive index.
Method of manipulating a laser beam of an optical tweezers system comprising a controllably deformable optical element, the method comprising the steps of:
- receiving a setpoint signal for a manipulation of said laser beam;
- calculating at least one drive signal for said optical element by means of a function mapping said setpoint to said drive signal;
- and
- driving said optical element with said signal coming from the optical tweezers system.
