UV and Visible Spectroscopy
Ultraviolet spectropolarimetry has produced some unexpected results from analysis of solar radiation, showing important information on aspects of the Sun’s magnetic field.
New miniature UV/vis spectrometer with high-sensitivity CMOS detector, acquisition speed up to 3000 scans s–1 and Ethernet and Wi-Fi communications. Wavelength range is configurable within 200–1100 nm An onboard buffer holds up to 50,000 spectra which prevents data loss during kinetics experiments.
Titanium dioxide (TiO2) is one of the most promising materials for photovoltaics and photocatalysis nowadays. This material appears in different crystalline forms, but the most attractive one for applications is “anatase”. EPFL scientists have now shed light onto the problem by a combination of steady-state and ultrafast spectroscopic techniques, as well as theoretical calculations...
Picoquant have introduced two new models from the PMA Hybrid Series, covering broad spectral ranges with high detection efficiency.
The 7205 UV/Visible spectrophotometer from Jenway has an extended wavelength range, down to 198 nm.
Jenway offers a range of visible and UV/visible spectrophotometers including single beam and diode array entry level spectrophotometers, split-beam spectrophotometers with a spectral bandwidth of 1.5nm; and advanced variable double beam spectrophotometers with a variable spectral bandwidth down to 0.5nm

Ibsen Photonics have announced a new line of OEM electronics for their spectrometers called DISP.
Biochrom introduces two new visible spectrophotometers to their WPA range: the WPA S800+ and S1200+.
Avantes’ new AvaSpec-HERO is based on a high-sensitivity, compact optical bench and a backthinned CCD detector.
To ensure that the removal and treatment of our sewerage meets increasingly high standards, it is important to be able to monitor the water online both to provide timely information and also to establish changing patterns over days, weeks and seasons. In their article “On-line monitoring for improved wastewater system management: applications of ultraviolet/visible spectroscopy”, Rita Brito,...
Specim have introduced the new range of AisaKESTREL pushbroom hyperspectral sensor systems.
Oriel Instruments has introduced the MS260i series of ¼-m imaging spectrographs.

Hamamatsu Photonics has introduced a new MEMS spectrometer, the C12880MA.
The new and improved S11850-1106 and S11851-1106 back-thinned CCD linear image sensors from Hamamatsu Photonics have improved etaloning characteristics and high sensitivity designed for spectrometry applications.
Scientists at Chalmers University of Technology, Sweden, have developed a new way to study nanoparticles one at a time using plasmonic nanospectroscopy, and have discovered that individual particles that may seem identical in fact can have very different properties. The results, which may prove to be important when developing new materials or applications such as hydrogen sensors for fuel cell...
Ibsen Photonics has announced the new Freedom HR-DUV spectrometer platform for integrators of compact analytical and process control instruments. It uses a new transmission grating, developed and manufactured by Ibsen Photonics. In contrast to typical blazed gratings, this new grating provides high and nearly constant diffraction efficiency over the entire 178–409 nm range for both...
Analytik Jena celebrates its 25th anniversary. As one of the first companies founded in East Germany after the fall of the Berlin wall, they have grown to offer a wide range of analytical products including a wide wide of atomic spectroscopy instrumentation.
tecSaaS from tec5 is a modular platform based on UV/vis/NIR spectroscopy for implementing stand-alone sensors with embedded processing for industrial or mobile applications. The on-board processing architecture with modular software/firmware processes the data of UV/vis/NIR spectral sensors in real time and only passes relevant results to the process interface. Complex algorithms such as...
Ocean Optics has introduced a line of accessories for dynamic sampling (averaging signal across the sample). The accessories are a diffuse reflectance (DR) probe, rotating sample cup, multiplexer and flow cell. The DR Probe integrates a light source and collection optics to measure 45° diffuse reflectance. The DynaCup is a rotating device that presents samples to the DR Probe. To save sample...
Hellma Analytics’ new UV/Vis/NIR optical immersion probe has been designed to meet the requirements for 3-A certification (a standard in the USA that defines hygiene criteria for technical equipment). This certification guarantees that all surfaces that come into contact with products are very easy to clean (CIP) and sterilise (SIP) according to 3-A standards. This makes it much easier for...
