We have a assembled a micro-spectroscopy setup by coupling an inverted microscope (Nikon Ti2U) to a spectrometer (Andor Kymera 328i with Newton 920 CCD). The system is capable of the following measurements
The typical working range of the setup is
(left) Optical setup (right) Raman spectrum of PDMS using 5 mW power.
(left) Dispersion setup (right) SPP dispersion on 60 nm gold film.
We use this home-made setup for measuring the dispersion diagram (reflectivity vs wavelength and angle of incidence) of surface plasmons. The setup consists of a theta-2theta stage from Holmarc which supports the cylindrical lens and sample of interest. White light illumination from a halogen source is directed to the sample using standard optical elements and the reflected light is analyzed using a spectrometer. The working range of the equipment is
The necessary facilities for synthesis of gold, silver and silica particles is available in lab. Further details to be uploaded soon.
PDMS based micro- and milli-fluidic channels are fabricated for lab-on-a-chip based devices for fast and label free detection of analytes. Further details to be uploaded soon.
