Polymer Analysis


Ocean Optics UV-Vis spectrometers, Raman instruments and NIR systems are excellent options for polymer characterization. Our modular spectrometers and accessories can be configured for applications as diverse as investigation of polymer molecular structure and degradation analysis of natural polymers. Our customers measured synthetic and natural polymers, including plastics such as polystyrene and polyvinyl chloride and materials such as cellulose and rubber.

With our modular approach, the instrumentation is robust and flexible enough for use in lab settings, on process lines and within other analytical devices. For example, polymers used in plastics have unique NIR spectral fingerprints that can be used for sorting and identifying polymer resins prior to extrusion and later for sorting of discarded products at recycling facilities. Similarly rich spectral features of various polymers can be obtained through UV-Vis spectroscopy and Raman analysis.

Example Setup: Raman Analysis of Polymers and Other Materials


Raman spectroscopy offers benefits for testing and characterization of a variety of materials including polymers, where it’s useful for investigating molecular structure. Like regular IR spectroscopy, Raman is rapid and non-destructive. Raman can capture data from a sample contained in plastic or other materials that are optically transparent to the wavelengths of interest.

Ocean Optics offers fully integrated Raman systems for handheld and laboratory applications, as well as modular setups anchored by our high-sensitivity CCD arrays. A modular setup is described here.


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 a LASER-785 series multimode laser. Options are available with FC or SMA 905 fiber-coupled output power. Custom excitation wavelengths are also available.

Raman setups typically include a probe and sample holder. In the example setup, we selected an RIP-RPB-785-SMA-FC fiber probe 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.


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.
