The Raman microprobe is a popular accessory for the RAMANRXN1™ analyzers. The Raman microprobe provides complementary microspectroscopy information on fundamental molecular vibrations to mid-infrared FT-IR microscopes. Using excitation wavelengths in the visible spectral region, a Raman microprobe is capable of analyzing diffraction-limited areas (typically 1 micron). The ability to both identify areas 10 times smaller in size than can be determined by FT-IR microscopy and the non-contact / no sample preparation nature of the technique are some of the many advantages of Raman microscopy.

The Raman microprobe can be configured with optional high-precision mapping stages and confocal optics to realize both surface and volumetric chemical imaging. The microprobe is offered as standard with a Class 1 laser radiation light shield for operation in a standard laboratory environment.

The combination of the fiber-coupled spectrometer and microscope in conjunction with a thermally stabilized microscope and high-precision motorized XYZ stage allows for routine collection of Raman images.

Kaiser's HoloMap™ software make real-time chemical images from Raman spectroscopy truly feasible.
