New High Performance Spectrometers
Our newest Ocean Optics spectrometers – the Ocean SR and Ocean HR series -- offer high resolution, high speed spectral acquisition and excellent signal-to-noise ratio performance to meet UV-Vis-NIR application needs.
In addition to restoring the iconic Ocean Optics brand of compact spectrometers, we have added two new families of spectrometers, with different models and wavelength-range options within each family. The result? You now enjoy a wider range of higher-performing spectrometers to meet your application needs.
In the tables below, we offer an overview of key characteristics for each spectrometer, with example applications for context. For assistance selecting the best spectrometer for your application, we highly recommend consulting an Ocean Optics Application Scientist.
Also, all Ocean Optics spectrometers now include OceanDirect, a powerful, cross-platform Software Developers Kit with an Application Programming Interface. OceanDirect enables High Speed Averaging Mode (HSAM), a hardware-accelerated signal averaging tool that dramatically enhances SNR per unit time. This promotes higher quality spectra and more accurate results.
