The modular confocal RAMAN micro-spectroscopy system is comprised of:

• Two spectrometers 

• Monochromatic light sources (Laser Diode): 405 nm, 532 nm and 785 nm.

• Objective turret (5x, 10x, 20x, 20x, 50x, 100 x and 63x H2O immersion lens).

• Modular system of: Optical couplers to spectrometers, monochromatic light optical inputs and CCD video camera coupling.

• Motorised platform system (X, Y and Z stepper motors) for positioning and focusing. 

• Scanning and micro-positioning system with electric piezo.

• Evaluation software (WITec Project) and system control (WITec control).

Operation Modes: 

• Raman spectral imaging: acquisition of a complete Raman spectrum in each pixel of the image.

• Flat (x-y direction) and depth (z-direction) scans with manual sample positioning.

• Image stacking: 3D confocal Raman imaging. 

• Time series.

• Single-point Raman spectrum acquisition.

• Single point depth profiling.

• Single-mode fibre-coupled UHTS spectrometer, specifically designed for Raman microscopy and low light intensity applications. 

• Brightfield microscopy. 

• TrueSurface: topographic Raman imaging.

• 3D Raman imaging.
