MultiRAM

The MultiRAM configuration provides a spectral range of 3600 – 50 cm^-1 (Stokes shift). The heart of the MultiRAM is Bruker’s patented interferometer with gold coated optics and permanent RockSolid^TM alignment, which provides the superb stability and throughput required for demanding emission experiments, as it is the case for Raman spectroscopy.

For ultimate flexibility, the MultiRAM can accommodate a second laser and detection system, automated polarization accessory, and two-fiber optic coupling ports. The large sample compartment is easily accessible from 3 sides and features switching to 90° scattering geometry, and defocusing optics which are essential for successful analysis of samples sensitive of thermal heating. A motorized sample stage for optimization of the sample position , and a white light source to correct the spectra for instrument responses are included in the standard configuration of the MultiRAM. Additional sampling accessories, such as automatic sample changers, low and high temperature stages are optional. The unique feature of the combination possibility with the FT-Raman microscope RamanScopeIII and Bruker’s compact Raman microscope SENTERRA II expands Raman spectroscopy to the microscale.

Equipped with a broad band quartz beamsplitter, Bruker’s patented and frictionless RockSolid interferometer guarantees highest sensitivity and stability. The Nd:YAG laser sample excitation source (1064 nm) is fully software controlled. The system can be equipped with either or both room-temperature InGaAs detector and a proprietary high-sensitivity Ge detector. High throughput optics and Bruker’s unique liquid nitrogen cooled Germanium diode detector offers ultra-low signal detection with minimal noise assuring excellent sensitivity. The long hold time of the refrigerant provides hassle free operation for an entire week.
