Optical/Micro Tweezers

optical tweezer is a scientific instrument that uses a focused laser beam to provide an attractive or repulsive force. Optical tweezers have been particularly successful in studying a variety of biological systems in recent years.

Equipment
The E3300 Optical Tweezer System is designed for single spot trapping and manipulation of micron sized particles. It is designed to be attached to a high quality commercial instrument, converting it into a Photonic Force Microscope (PFM).
For the advanced researcher a number of different breadboard-based custom systems can be configured using an open architecture format for laboratory environments. This range of systems can cater for the many variations needed by users of optical trapping equipment.
Many researchers wish to measure trapping force: so by imaging an interference pattern onto a quadrant photodetector (QPD) and utilising dedicated software, an operator can monitor the position of a trapped particle with nanometer resolution.
The E3500 Optical Tweezer 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.
PALM MicroTweezers, also known as optical tweezers, is a highly effective and non-invasive method to trap, move or manipulate microscopic particles such as cells, crystals, beads or even sub-cellular structures.
The new generation of multibeam optical tweezers. The Molecular Machines & Industries CellManipulator is an optical trap that enables ultraprecise, contact-free manipulation of microscopic particles. The optical tweezers use a focused laser beam to trap, move and position single cells or sub-cellular and microscopic particles in a size range of approximately 0.1 micro - 200 micro.
