E3500 Series Multiple Spot Optical Tweezers Systems

The E3500 Optical Tweezers System is a fully functional computer controlled unit for the multiple spot trapping and manipulation of micron sized particles。 It is designed to be attached to high quality commercial instruments, upgrading them to Photonic Force Microscopes, especially useful in mechanobiology experiments and biomechanics。

The ease of use and flexibility of the system allow many optical trapping experiments to be undertaken. In biophysics for example, with applications such as cell sorting and microrheology. In chemistry, for colloid research, and in physics for particle spectroscopy.
