Abstract
Ocean Optics Launches STS-UV Microspectrometer
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 × 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 characterisation. 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-infrared (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 complementary metal-oxide semiconductor (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 stay 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 dynamic link libraries (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.

Benrhos develops ice point bath for supermarkets
Benrhos supplies specialist temperature products and advice for technically demanding applications such as their latest very low cost portable ice/water bath for checking thermometers at 0°C. A large supermarket chain required a simple device for regular checking of its hand held thermometers used for in-store temperature monitoring of cooked, chilled and frozen foods.
The design criteria were an accuracy of 0° ±0.3°C, simple to use, easily portable and low cost. The technical problems that needed to be overcome to achieve the required accuracy were that the ice/water mixture must be constantly stirred and kept aerated in order to get a reliable 0°C.
The result is the Mini-Zero Ice Point Bath which can be easily held in one hand, is powered by a 1.5v C-type battery and uses easily obtainable ice cubes. The technical problems were overcome by bubbling air through the ice/water mixture to both stir and aerate it. By using a simple elegant design the cost of a Mini-Zero can be kept at a reasonable level even for small quantities.
