Raman Spectrometers

Raman spectroscopy is a powerful spectroscopic technique used to observe vibrational and rotational modes in a molecular system. Raman spectroscopy is commonly used in chemistry to provide a fingerprint by which molecules can be identified.

Typically, a sample is illuminated with a laser beam (we use in our system 532nm or 785nm). Electromagnetic radiation from the illuminated spot is collected with a lens (microscope objective in our systems) and sent through a spectrometer. Elastic scattered radiation at the wavelength corresponding to the laser line (Rayleigh scattering) is filtered out by either a notch filter by specifically selected beam splitter and an adequate band pass filter, while the rest of the collected light (Raman scattered) is dispersed onto a detector.

In the Thunder Optics Raman product line we have high-performance modular Raman systems (Isim Raman System), LowCost Raman systems for hobbyists (Gem Raman System) and an intermediate range for education purpose (Almad Raman System). For each quality category we use the adapted optics quality.

Our policy is to reach all budgets and let everyone use the Raman Spectroscopy at his level. Even our LowCost Gem Raman system permits to get very good spectra of gems, mineral and stones).

You have also the possibility to combine every part of our modular Raman systems (Lasers, Probes and Spectrometers) to build your specific spectrometer adapted to your need and budget. Our technical staff will help you and answer your question to help you build your desired apparatus.
