Spectrometer provides full spectral UV analysis in a tiny footprint

Paul Boughton

Designed for integration into spectroscopy instrumentation, medical devices, process monitoring and other applications where a small footprint is desired, the STS-UV Microspectrometer from Ocean Optics is a compact yet high-performance spectrometer.

Measuring just 40 mm x 42 mm and 24 mm high, this product is optimised for applications in the ultraviolet (190-650 nm) including absorbance measurements, point of care diagnostics, emission spectroscopy and laser characteridation.

The STS-UV provides powerful performance for full spectral analysis enabling applications where a range of the spectrum is necessary for proper measurements.

The high signal to noise and wide dynamic range make the STS-UV useful for demanding measurements such as determining the absorbance from dilute solutions. A selection of configurations allows users to optimise optical resolution to a specific application.

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. All versions feature the same form factor and comparable performance specifications.

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. For example, excellent linearity, absorbance repeatability and wavelength accuracy ensure reproducibility even in large production quantities. In addition, high thermal stability performance and low baseline drift ensure that data stays accurate, even under changing environmental conditions.

The STS-UV easily integrates into other devices or can be set up next to a process line for quality control measurements or as part of a lab station. Several software control options, from drivers for LabVIEW and MATLAB to DLLs for direct control of the spectrometer in Java, Linux or Windows, allow users to seamlessly integrate STS. For laboratory experiments, all STS spectrometers are compatible with Ocean Optics’ OceanView spectroscopy software.
