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.

The ST series is a family of compact, high performance, cost-effective spectrometers ideal for embedding into OEM devices. The ST models are an attractive option for applications such as LED characterization, absorbance and transmission measurements. Life sciences, materials identification, environmental monitoring, quality control and process monitoring are among some of the applications where the ST has played its role of a powerful performer in a small footprint. The ST delivers optical resolution, sensitivity and stability associated with larger, more expensive spectrometers.
