OCEAN-ST Microspectrometer / Spectrometers

The new ST microspectrometer provides excellent spectral performance in an ultra-compact footprint. It is ideal for both everyday lab use and embedded applications.

OCEAN-ST Microspectrometer summary

This new range of powerful microspectrometers are available in the UV (185-660nm), Vis (350-810nm) and NIR (645-1085nm) wavelengths. They provide excellent spectral response, high-speed spectral acquisition, and high signal to noise ratio performance. Despite their small size and light weight, ST microspectrometers deliver full spectral analysis at a performance level comparable to larger optical bench spectrometers.
