An optical tweezer is a system designed to trap and manipulate micro or nanoscopic objects without touching them. They are based on the energy contained in the light and the force that the photons are able to exert on these objects. Spatial Light Modulator (SLM) allows the creation  of several traps (laser impacts) simultaneously, up to 1000 in some systems.

Our TWIN WAVELENGTH module is an alternative to the fixed optical tweezer .

The use of galvanometric mirrors allows the simultaneous application of adhesion force measurements by FRET.

An optical tweezer multiplexing Two balls therefore consists on:

-a laser source

-Focus components, beam separation and deviation

-a spatial light modulator and its piloting device
