Product Details


Ocean ST is a powerful Shortwave NIR microspectrometer (~645-1085 nm) that provides rapid 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 microspectrometer is ideal for both everyday lab use and integration into other devices and setups where space is limited. Shortwave NIR applications range from absorbance of liquids (water quality) to reflection of solid surfaces (product authentication).

Software Developers Kit Adds Value
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 optimize spectrometer performance and access critical data for analysis.

With OceanDirect, users can control how they apply spectral data to application challenges, whether conducting academic research, performing product development and integration, or monitoring industrial processes.
