Ocean ST series – Microspectrometer

Enhanced Spectral Performance in a Compact Footprint

Ocean ST is a powerful microspectrometer that provides excellent UV response, high-speed spectral acquisition, and high signal to noise ratio performance in an ultra-compact footprint. Despite its small size and light weight, Ocean ST delivers full spectral analysis at a performance level comparable to larger and more expensive spectrometers. This powerful microspectrometer is ideal for both everyday lab use and integration into other devices and setups where space is limited. Applications range from DNA absorbance to colour characterisation.

Each Ocean ST also includes OceanDirect, a powerful, cross-platform Software Developers Kit. 

  • Ultra-compact – Instrument footprint less than 45 mm square
  • Remarkable performance – Full spectral analysis with the dynamic range and SNR characteristics of a large-bench spectrometer
  • Rugged connectors – Robust USB Type-C and electronic accessory connectors ensure reliable performance

Preconfigured Models:

ST-UV-25185-650 nm2.2 nm
ST-VIS-25350-810 nm2.2 nm
ST-NIR-25645-1085 nm2.2 nm

Ocean ST MicroSpectrometer

Ocean ST microspectrometer options are available for UV, visible and shortwave NIR wavelength coverage, offering great application flexibility. Also, the replaceable slit design allows users to optimize the optical resolution and throughput of their setup. Choose a narrow slit width for light-rich applications where resolution is most important. For low-light applications, select a wider entrance slit to allow more light into the spectrometer.

The Ocean ST microspectrometer is compatible with Ocean Optics light sources, accessories and OceanView software, allowing users to mix and match components for different applications. Its rugged design, thermal stability and unit-to-unit reproducibility make the Ocean ST microspectrometer an appealing choice for embedding into other instrumentation, inline process operations, and at-line quality control stations.

Each Ocean ST microspectrometer comes with OceanDirect, a powerful, cross-platform Software Developers Kit (SDK) with an Application Programming Interface (API). With its library of functions, OceanDirect makes it possible for users to 0ptimise spectrometer performance and access critical data for analysis.
