Description
The Ocean ST UV Microspectrometer is an ultra-compact (42 × 40 × 26 mm), high-SNR (up to 2250:1) instrument optimized for ultraviolet measurements, covering 185–400 nm. With USB-C connectivity, superior thermal stability, and the OceanDirect™ SDK, it is ideal for DNA absorbance, protein analysis, environmental monitoring, and OEM integration requiring reliable UV performance.
Despite its small footprint, the Ocean ST UV delivers high-quality spectral analysis with performance comparable to larger, more expensive spectrometers. Its compact and rugged design makes it well-suited for everyday laboratory use, field applications, or integration into devices and setups where space is limited.
Designed for adaptability, the Ocean ST UV features a replaceable slit design that enables users to balance optical resolution and throughput for both strong and low-light UV applications. This flexibility ensures accurate, reproducible results across a wide range of scientific and industrial use cases.
Compatibility with Ocean Optics light sources, optical accessories, and OceanView software enhances the utility of the Ocean ST UV, while its excellent thermal stability and unit-to-unit reproducibility make it a dependable choice for embedding into instrumentation, inline process operations, and at-line quality control.
Each Ocean ST UV spectrometer is supplied with OceanDirect™, a powerful Software Developers Kit (SDK) that includes an Application Programming Interface (API). This toolkit allows users to control performance parameters, automate workflows, and access critical spectral data for deeper analysis, making the Ocean ST UV an exceptional value in a compact package.
