Optical Workstation


This is a custom built multiphoton laser scanning system built around a Nikon TE300 inverted microscope. The system features dual galvos for simultaneous imaging and photomanipulation, three lasers and time-domain fluorescence lifetime. 

Class IV Laser: 

OWS Button


The OWS is the system most often used by collaborators.  Experiments often run on the OWS include collagen imaging of tumor sections using second harmonic generation, lifetime imaging, and imaging of autofluorescent molecules such as NADH.
