MKS Instruments has partnered with Edmund Optics^® (EO) to provide global access to their Richardson Gratings™ high-precision ruled and holographic gratings. EO is now a global distributor of Richardson Gratings products and offers a large selection of gratings in-stock and ready to ship.

By employing a novel phase-matching scheme in four-wave mixing, they could compress the spectral width of the initial broadband light by more than hundred times. The detailed experimental and theoretical resultshave been published in Nature Photonics.

Recently, Prof. GAO Xiaoming's group from the Anhui Institute of Optics and Fine Mechanics (AIOFM) of the Hefei Institutes of Physical Science (HFIPS) demonstrated how they designed and manufactured a photoacoustic spectroscopy based sensor to measure aerosols and nitrogen dioxide (NO₂) simultaneously.

Researchers from CIC nanoGUNE BRTA (San Sebastian, Spain), in collaboration with the Donostia International Physics Center (San Sebastián, Spain) and the University of Oviedo (Spain) employed a spectroscopic nanoimaging technique to study how infrared nanolight - in form of phonon polaritons - and molecular vibrations interact with each other.

Tohoku University researchers have improved a method for probing semiconducting crystals with light to detect defects and impurities. The details of their 'omnidirectional photoluminescence (ODPL) spectroscopy' set-up were published in the journal Applied Physics Express, and could help improve the fabrication of materials for electric cars and solar cells.

UniKLasers Limited, a leading manufacturer of high precision scientific laser instrumentation, has launched a second-generation series of its Solo 640 range of laser equipment, offering greater precision and feature enhancement in areas reliant on single frequency laser technology such as high-resolution Holography, Interferometry, Raman and Brillouin Spectroscopy.

With high-resolution microscopy, it is theoretically possible to image cell structures with a resolution of a few nanometres. However, this has not yet been possible in practice.

Hyperspectral imaging technology has advanced significantly in the last 50 years, and Greg Staples with Bayspec talked with us for a few minutes at the 2016 SPIE DCS exhibition about how it has changed.

This year at Photonics West, Jason Palidwar with Iridian Spectral Technologies gave us insight into the three optical filtering solutions his company is focusing on in 2016.

Si-Ware Systems drew a lot of positive attention at Photonics West 2015 with their Prism award winning MEMS spectral sensors. Bassam Saadany and Mostafa Medhat met with Photonics Online on the last day of the show so we could get a glimpse of the sensors in person and see them in action. If you’re looking to replace your standard bench top FT-IR spectrometer with something much smaller and much less expensive, then this video is most certainly for you.

PD-LD's LS-2 LabSource is a dual-source benchtop module features two laser sources, rendering it unique relative to other benchtop Raman modules. These laser sources are VBG-stabilized, and are available in standard and custom wavelengths.

Watch this video from Avantes for news on a recent redesign of their tungsten-halogen light source, some beam splitter combiner accessories, and the latest addition to their line of high-sensitivity spectrometers.

Bob Struthers of PD-LD introduces us to its new 530nm green laser at Photonics West 2013.

Ed Albe and Jeffrey Meade of Tornado Spectral Systems tell us about the HyperFlux U1 HTVS (high throughput virtual slit) enabled spectrometer at Photonics West 2013.
