Description
The Ocean ST VIS Microspectrometer is an ultra-compact (42 × 40 × 26 mm), high-SNR (up to 2250:1) instrument optimized for visible light measurements, covering 350–800 nm. With USB-C connectivity, superior thermal stability, and the OceanDirect™ SDK, it is ideal for applications such as LED and display characterization, color measurement, reflectance and transmittance studies, and OEM integration where compact, reliable VIS performance is essential.
Despite its small footprint, the Ocean ST VIS delivers full spectral analysis with performance levels comparable to larger, more costly spectrometers. Its rugged and space-saving design makes it a strong choice for laboratory workflows, quality control stations, or integration into portable and embedded devices where space is at a premium.
The Ocean ST VIS incorporates a replaceable slit design, giving users flexibility to optimize spectral resolution and throughput for both high-light and low-light visible applications. This ensures reproducible and accurate results tailored to diverse measurement needs.
Compatibility with Ocean Optics light sources, accessories, and OceanView software enhances its versatility, while robust thermal stability and unit-to-unit reproducibility make it reliable for demanding environments. It is equally effective for standalone laboratory use, inline process monitoring, or embedding into OEM instrumentation.
Each Ocean ST VIS spectrometer is supplied with OceanDirect™, a comprehensive Software Developers Kit (SDK) that includes an Application Programming Interface (API). This empowers users to automate workflows, fine-tune acquisition parameters, and integrate spectral data directly into custom applications, maximizing the value of this compact, high-performance VIS spectrometer.
