High Quality Optics in a High Performance FT-Raman Spectrometer - the MultiRAM from Bruker

OPUS software is intuitive, easy-to-use and controls all data collection and manipulation functions for the MultiRAM Stand Alone FT-Raman Spectrometer. Enabling software control of analysis conditions, the real-time spectrum display also facilitates optimization of the laser power and the sample position.

High Performance – The high performance FT-Raman system combines advanced digital electronics with Bruker Optics’ high quality optics. At the MultiRAM’s heart lies Bruker Optics’ patented interferometer – equipped with gold-coated optics and permanent RockSolid alignment, providing superb stability and throughput, which are essential ingredients for demanding emission experiments.

Sampling Flexibility – The MultiRAM can accommodate a second laser and detection system, automated polarization accessory, and two-fiber optic coupling ports, thus ensuring ultimate flexibility. What’s more, it features an easy switch between 90° and 180° scattering geometry, and defocusing optics (a prerequisite for colored samples which heat up by laser beam).

The standard configuration of the MultiRAM also includes a motorized sample stage (useful for sample position optimization), and a white light source (which corrects the spectra for instrument responses).

Optional add-ons include additional sampling accessories, such as automatic sample changers, and low and high temperature stages. What’s more, with the FT-Raman microscope RamanScope, FT-Raman FT-Raman spectroscopy is expanded to samples in the µm size range.

Sensitivity and Stability – The MultiRAM configuration provides a spectral range of 3600 – 50 cm-1 (Stokes shift). Bruker Optics‘ patented and frictionless RockSolid interferometer is equipped with a broad-range quartz beamsplitter, thereby providing high sensitivity and stability.

In addition, the standard diode-pumped Nd:YAG laser source (1064 nm) is air-cooled and fully software controlled. The system has the option to be fitted with either or both room-temperature InGaAs detector and a proprietary high-sensitivity Ge diode detector.

What’s more, Bruker Optics’ unique liquid nitrogen cooled Germanium detector and high throughput optics offer ultra-low signal detection with minimal noise, thus assuring excellent sensitivity. Ultimately, the long hold time of the refrigerant ensures hassle-free operation all week-long.
