Introduction
The Centice Multimodal Multiplex Sampling (MMS) Raman spectrometer provides significantly higher
measurement sensitivity than a conventional grating based slit entrance spectrometer due to its unique
multimodal multiplex sampling (MMS) technology. An MMS-based spectrometer samples nearly 1,000
optical channels simultaneously through a large area coded aperture – instead of a slit – then applies
proprietary algorithms to precisely construct the spectral content of a source. With MMS technology, both
high resolution and high light throughput can be achieved simultaneously in a single shot measurement.
SpectraSuite software is available with this spectrometer to aid you with your spectral analysis.
The Centice Raman spectrometer is designed to be easy to use and operate with minimal set-up. Follow
the detailed step by step instructions described in this chapter to install the spectrometer.
Applications
MMS-based instruments are ideal for measuring weak, scattering and diffuse sources and samples
because the spectrometer can collect and process far more light through its wide area aperture, without
affecting spectral resolution.
Key applications include material inspection, identification of unknown materials, and quantitative
analysis of both intermediates and final products in the chemical and pharmaceutical industries. Any
material that is Raman-active and fits within the sample chamber of the instrument can be measured.
Typical samples include powders, liquids and polymers. The system is also ideal for teaching and
research applications in colleges and universities.
The MMS system uses a wide-area aperture that cannot be illuminated effectively with a fiber input. The
aperture should be slightly overfilled to obtain the best spectrum. The wide-area aperture and grating
cannot be changed. The MMS aperture and grating are designed specifically for the detector. For fiber-
based Raman analysis, consider our .
