Facility Features, Working Principle and Specifications
Working Principle:
Light reflected of Raman-active samples irradiated with monochromatic radiation consists of a Raman component having slightly different wavelength as compared to that of the incident radiation. A spectrometer and detector are used to measure intensity of reflected light and it's corresponding wavelength to give us Raman spectrum for the sample.
Features:
Following measurements can be performed using Raman/PL signal-
- Spectral Analysis
- Mapping
- Depth Profiling
Aforementioned measurements can also be performed-
- While varying temperature (Temperature-dependent Analysis)
- While varying degree of polarization / orientation of sample (Polarization-dependent Analysis)
- At specific intervals of time (Time-dependent Analysis)
Specifications:
Spectral Range of System
- Raman - 75 to 4000 cm-1
- PL - 330 to 1600 nm
Motorized Stage
- Maximum travel distance of 110 mm x 75 mm x 25 mm with minimum step size of 50 nm x 50 nm x 10 nm.
- Minimum step-size for mapping is 100 nm.
Range for Temperature-dependent Analysis
- 300K to 12K (using CCR)
- 300K to 1200K (using furnace)
Polarization-dependent Analysis
- Incident light can be polarized as normal, orthogonal or circular.
- Reflected light can be polarized at any angle.
Additional measurements
- Low-wavenumber analysis from 15 cm-1 using LWN filter.
- Fiber-optic probe for analysis of samples which cannot be directly placed on the microscope stage.
Sample Preparation, User Instructions and Precautionary Measures
• Maximum size of sample which can be placed on the microscope stage is 50 mm x 50 mm x 30 mm.
• For temperature-dependent studies sample size should be less than 3 mm x 3 mm x 3 mm.
• If possible, use of coolants/lubricants should be avoided when resizing the samples.
• Sample should remain stable upon exposure to high intensity laser beam.
• For low-temperature analysis, sample must be able to withstand high vacuum conditions.
• For high-temperature analysis, sample should not deform or emit fumes as temperature is increased.
• System’s optical microscope may not be able to acquire data from particles/structures having size less than 100 nanometers.
