Chemistry
Ocean Optics modular spectrometers and accessories comprise a flexible toolkit for chemists seeking to understand and monitor how light interacts with matter. Chemical composition, analyte concentration and molecular structure are all readily measured with spectroscopy. Easily configure setups for UV-Vis and NIR absorbance, fluorescence and Raman.

Example Setup: Raman Analysis
Overview
Raman spectroscopy offers benefits for testing and characterization of chemical samples. Like IR spectroscopy, Raman is rapid and non-destructive. It can capture data from a sample contained in plastic or other materials that are optically transparent to the wavelengths of interest.
Ocean Optics offers a range of fully integrated Raman systems for handheld and laboratory applications, as well as modular setups anchored by our high-sensitivity, back-thinned CCD arrays. One such modular setup is described here.
Spectrometer
We offer a QE series spectrometer that’s preconfigured for 785 nm Raman analysis, making it an excellent option for chemical identification and fingerprinting. The spectrometer is preset with a grating optimized for Raman response, gold mirrors to increase sensitivity in the optical bench, and a 50 µm slit to maintain good resolution. The setup provides coverage from ~780-1100 nm.
Excitation Laser and Sampling Optics
For 785 nm Raman excitation, we recommend one of our LASER-785 series multimode lasers. Options are available with FC or SMA fiber-coupled output power. Custom excitation ranges are also available.
Raman accessories typically include a probe and sample holder. In the example setup, we selected an RIP-RPB-785-SMA-FC and the RIP-PA-SH Raman sample holder. Safety glasses (LASER-GL-ML1), which are suitable for use with 785 nm, 808 nm and 1064 nm lasers, complete the system.
Software
OceanView spectroscopy software supports Raman experiments, but for more advanced analysis we recommend an add-on chemometrics package such as the RAM-ANIQ-LAB analytical chemistry option.
