The Centre is well equipped,
including a Class 3500 clean laboratory for soft-condensed matter and functional
materials research and applications.
Facilities
The Centre for Biophotonics and Laser Science is well equipped with
lasers, spectroscopy systems and associated devices in dedicated experimental
laboratories. The laser systems enable us to access wavelengths from 157
nm – 2500 nm. We have pulsed systems with pulse durations down to 130 femtoseconds
for ultrafast spectroscopy, as well as high power CW systems. A range of
detectors, including cooled photon counting detectors and an intensified
CCD camera, enable sensitive detection with imaging, spectrally resolved
and time resolved capabilities. We have 3 dedicated laser tweezers systems,
and a confocal microscope system with fluorescence imaging capabilities.
The Centre has a class 3500 clean laboratory, and a polymer and general synthesis
laboratory for sample preparation.
