The RamanMicro 200
The RamanMicro 200 is a Raman microscope system with laser excitation wavelength at
785 nm.
Figure 9 The RamanMicro 200 microscope
The microscope (Figure 9) is composed of a frame, illumination module, Raman module and
camera module. This is connected to the spectrometer module by two fiber optic cables. The
spectrometer module contains the spectrograph and CCD detector. The laser supplies light
through an objective lens onto the sample. The scattered light from the sample is collected
with the same objective lens and transmitted back to the spectrometer. A schematic of the
system configuration is provided in Figure 10.
