A colleague from the Crick has an optical tweezers system on offer for a good price, please see below Best wishes Andreas ---------------------------------------------------- From: Nicholas Cade [mailto:Nicholas.Cade@crick.ac.uk] Sent: 06 October 2016 11:17 To: Bruckbauer, Andreas <a.bruckbauer@imperial.ac.uk> Subject: JPK optical tweezers Unfortunately we won't be able to take our optical trap with us when we move into the new building, and I've been trying to find a new home for it. None of the other groups joining us will have the space for it. Do you know anybody at Imperial that might be interested? I've put the details below and attached the original quotation showing the system specifications - please feel free to forward this email. I'm told we only need to recover the depreciated value (~£25k). http://www.jpk.com/sid9a4635252f2abd32eabb745c5046bce7/nanotracker-2-overvie... Some of the key features are: · 3W 1064nm trapping laser · Two independent trapping beams with full range of power splitting between the two. · One beam can be split into additional multiplexed traps using an AOD · Three dimensional trap position control, independent of observation plane · Two independent detection modules for each beam, each with separate QPD (xy) and photodiode (z) · Full access to all signals for further external control / monitoring Fully software controlled experiments for · Automatic calibration of trap stiffness · Force spectroscopy (particle moving in a fixed trap) · Force-feedback particle tracking at arbitrary angles We are under some time pressure to decide on the fate of the system as we move at the end of October and obviously if anyone wanted to see the system working it would need to be done before then.
