Innovation through Spectroscopy

Spectra Solutions Inc. (SSI) is a leading manufacturer of spectroscopic analytical instruments and fiber optic Raman probes to industrial companies and scientific research institutions worldwide. We are located  just outside of Boston, MA, in the Route 128 technology corridor. Our company's mission is to develop Raman instrumentation to evolve and solve a magnitude of worldwide problems in all industries.  We customize spectroscopic instruments to provide solutions to critical problems from detecting oil spill in the ocean, nuclear fabrication and reprocessing, and gem analysis.

Our Raman Monitoring System (RAMS) process instruments are unique in that they have the capability to monitor up to 6 probes simultaneously.  We offer multiple spectroscopic accessories such as Raman microscope with CMOS video camera, flow cells for process applications, fiber optic cables, and multi-port fiber optic feed through flanges.  We also work with clients with custom needs to develop custom spectroscopic instruments and fiber optic probes to meet each specific application. 

Our research collaboration with a US Department of Energy national laboratory puts us at the forefront in applying Raman spectroscopic analysis to nuclear materials. Using our RAMS instruments and Raman probes, process analysis of nuclear fuel reprocessing has been developed with the capability of monitoring multiple points in the process stream. Chemometric models integrated with our SpectraChem plug-in chemometrics software have been developed for this process. Ongoing research applies Raman and absorption analysis to the microfluidic domain for application in nuclear fuel analysis and process modeling.

Our Products

Raman Probes

Our Raman probes employ backscattering optical design that utilizes high throughput miniature optical components. We offer general purpose laboratory, immersion and process probes with removable focusing lens barrel.


Our Raman spectrographs employ high throughput volume phase holographic (VPH) grating and deep cooling, 2-dimensional CCD detector. F2 optics are utilized to better match the optical fiber input to the spectrograph. 

Raman Systems

Our Raman instruments incorporate our VPH grating spectrograph, wavelength stabilized lasers, electronics and software to control the operation of Raman measurements. We offer portable and rack mount Raman instruments that are available in multiple channel operation.


Our Raman spectrographs and instruments can be controlled with our SpectraSoft data acquisition software. SpectraSoft has several acquisition modes. Our SpectraChem software is a chemometric analysis and process monitoring plug-in to SpectraSoft that allows the integration of SpectraSoft with MATLAB or with Solo Predictor Engine.


Our fiber optic coupled microscopes can be used with our spectrographs and Raman instruments or any other Raman instruments that have optical fiber input. Single channel and dual laser excitation microscopes are available. The dual laser microscope allows the simultaneous Raman measurement of the same sample spot at 2 laser wavelengths.


Our lasers have narrow linewidth that is ideal for Raman measurements. Lasers are available at 532 nm and 785 nm wavelengths. The 532 nm laser is a diode-pumped solid-state (DPSS) laser and the 785 nm laser is wavelength stabilized laser.


A variety of accessories are available for our Raman instruments and probes. This includes our probe sample holder, focusing lens barrel (wide variety of materials, lengths and focal lengths), Raman microscope, optical fiber cables, and flow cells.


We offer custom design of fiber optic probes (Raman, absorption, fluorescence and reflectance) that fits your applications. Custom probe interface for vacuum and high pressure environments have been designed for previous clients.
