Request InfoElliot Scientific Ltd.HARPENDEN, UK, Jan. 28, 2010 – Elliot Scientific Ltd. has introduced a new version of its E3500 computer-controlled multiple-trap optical tweezer system with E4100 quadrant photodetector (QPD) force measurement capability. The system uses two fiber-coupled lasers: one for trapping and the other for the probe beam. It comprises an optical module containing the laser, beam-steering optics, a microscope interface, a control module with drive electronics, a computer and control software. Also included are a computer monitor and a laser blocking filter. The tweezer was built into a high-end Nikon microscope.
