The STS-UV Microspectrometer from Ocean Optics (Dunedin, FL) is a compact, high-performance spectrometer. Measuring just 40mm x 42mm and 24mm high, this product is optimized for applications in the ultraviolet (190-650 nm) including absorbance measurements, point of care diagnostics, emission spectroscopy and laser characterization. The STS-UV is anchored by a 1024- element detector in a crossed Czerny Turner optical bench. Its optical design and advanced CMOS detector elevate STS to performance levels comparable to larger and more expensive spectrometers. Previously released versions of the STS are also available for the visible (350-800 nm) and shortwave near-IR (650-1100 nm) regions of the spectrum.
