The LabRAM HR Evolution Confocal Raman Microscope provides measurements of spectra and 2-d mapping of true confocal Raman and photoluminescence in the range from near- IR to UV. The instrument contains 4 excitation sources and has fast mapping mode.
This is an accordion element with a series of buttons that open and close related content panels.
Configuration
- Provide measurements of spectra and 2-d mapping of true confocal Raman and photoluminescence in the range from near- IR to 405nm
- Spatial resolution: Diffraction limited; <300 nm @ 532 nm laser for xy- directions and <600 nm for z direction for appropriate samples
- Spectral resolution: ~0.3 cm-1 for 633nm -estimation done for 1800 line/mm grating
- Automated Pass Filter Selection – the motorized pass filter selector enables 4 laser wavelengths, 405 nm, 532 nm, 633nm, and 785nm
- 800 mm spectrograph for high resolution
- Three gratings: 300, 600, and 1800 for different spectral range and spectral resolution
- Fast Raman images using CCD detector and scanning stage or using the Duo scan option where the laser is swept
- Primary detector: SynapsePlus BIDD CCD detector, QE~90% in the range 400-800 nm, QE above 50% at 950nm
- Second detector: InGaAs for IR for 700 to 1800nm with Quantum Efficiency ~90%
- XYZ Stage and Duo scan option for laser sweeping
- Heating/cooling stage: Linkam-600 a computer controlled heating and cooling stage, Temperature from -196 oC to 600 oC
- Automatic switching between lasers and filters
- Polarizers for incident and reflected light may be inserted upon request
- Microscope objectives include 10x, 50x, 100x and 50x far field (for use with the Linkam stage)
