Current Work
- use cage system for more robust setup - integrate visible laser for easier alignment - compress beam expander and enclose in tube - use new stages
 * redesign of optical trap

Completed Tasks
--measure step sizes with particle tracking software --verify that data is correct
 * new stages for the optical traps (motors are too week for current stages)


 * built new light sources for optical traps and DNA melting lab


 * making boxes for new optical traps


 * building new optical trap


 * 20.309 optical trapping lab

allow enough time for the transient response before collecting data
 * upgrading Stokes VI

-combined the two with a 'sequence structure'
 * integrating power meter in QPD alignment VI

-faulty QPD. Does not output (0,0) when there is no light.
 * troubleshooting 'wind' trap

Future Goals
- fab new cantilevers - implement range of cantilever lengths - calibration done by heating cantilever with laser - try various viscosity environment
 * Design new instument for boltzman constant lab

Possible Projects

 * redesign mounting for optical trap's circuit boards
 * use PSD instead of QPD and redesign board
