Optical spectroscopy setup

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

  • Bright-field transmission/reflection spectroscopy
  • Dark-field transmission spectroscopy
  • Raman spectroscopy

The typical working range of the setup is

  • Wavelength: 400-1000 nm
  • Gratings: 150 l/mm, 600 l/mm, 1200 l/mm
  • Raman laser wavelength & power: 594 nm & 100 mW
  • Raman spectroscopy range: 250 cm-1 to 3500 cm-1

Dispersion measurement setup

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

  • Wavelength: 500-850 nm
  • Angle: 30 deg - 70 deg

Chemical synthesis of nano- and micro-particles

The necessary facilities for synthesis of gold, silver and silica particles is available in lab. Further details to be uploaded soon.

Micro- and milli-fluidic devices

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.
