  • E4100 QPD Force Measurement System

    • QPD Equipped Optical Tweezer System with Force Measurement

    Many researchers wish to measure trapping force, so we have developed particle imaging upon a quadrant photodetector (QPD) and dedicated software to allow an operator to monitor the position of a trapped particle to nanometer accuracy.

     

    The measurement software also allows the user to calibrate the motion of a single trapped object and thus makes it possible to infer forces exerted — this makes optical tweezing particularly attractive for a growing number of scientists probing single-molecule systems.

     

    Several different configurations to match possible user requirements are available within the E4100 range. Elliot Scientific can supply a complete Force Measurement Optical Tweezer plug'n'play system, or this capability can be added to an existing tweezer installation.

     

    Retrofitting to a good quality microscope is also a viable alternative if there are budget limitations.

     

    Multiple QPDs and/or an auxiliary probe beam are among a number of options also on offer.
