Raman Microscope system with Chemical Mapping Functionalities
and Optical Microscopes

(Thermo Scientific)

Features
  • Excitation source: Laser (λ = 780 nm laser)
  • spectral resolution: 1cm-1
  • spatial resolution: 2 microns

Raman Microscope system embeds both micro-spectroscopy capability and automated Chemical mapping functionality for molecular finger-printing.
It also has a huge spectral database that allows the user to screen multiple components for faster identification of materials of interest.
Non-ambient measurements are possible.
This platform is extensively used for characterizing functional materials (at different length scales) used in various applications like Catalysis, Pharmaceuticals, Nutraceutical & Natural Products, Biomedical, Sensors.

Raman Imaging & Spectroscopy

Raman microscope set-up that facilitates the understanding of structure-property correlation in functional materials has been established. This facility promotes inter-departmental research activity and enhances the material characterization capability pertaining to a wide variety of applications that include energy harvesting & storage; photonics; piezoelectric, thermoelectric, biomedical etc. This set-up indeed helps in identifying molecular groups prevailing in a given material.

Fiber Optic Gyroscopes

The faculty at the Department of Physics are working on the development of novel fiber optic gyroscopes housing a strong reflecting element sandwiched between fiber optic connectors to create an optical discontinuity in the path of the fiber optic resonator.

Multi-modal Microscope

Multimodal optical microscope as a cost effective disease diagnostic as well as an essential research and teaching tool has been demonstrated. This optical microscope possesses multiple functionalities like Bright Field imaging; Phase Contrasting; Edge enhancement and Fluorescence imaging: all these are provided in a single platform. The primary necessity for developing such a device arises from the growing need for affordable diagnostic tools in India.
