Using 1064 nm Dispersive Raman For Ink And Paint Classification
Using 1064 nm Dispersive Raman For Ink And Paint Classification
 In the past, Raman spectroscopy was not useful for forensics because most "real-world" samples have a vivid color, whose fluorescence could overwhelm Raman signals. This issue is resolved by BaySpec’s1064 nm excitation dispersive Raman systems that offer maximum reduction in fluorescence interference.  Continue Reading..

SPECTROSCOPY PRODUCTS

Opto Diode presents a new, two-stage, cooled, lead selenide (PbSe) detector that operates in the mid-infrared (IR) spectral region with peak sensitivity between 4.3 and 4.5µm. The cooler on the BXT2S-28T allows the detector element to operate as low as -45 °C to maximize detectivity (D*).

The IR Detectors (B Series) from Opto Diode are high-performance lead selenide (PbSe) single-channel, cooled and uncooled devices. Applications for these detectors include gas analysis, emissions monitoring, spectroscopy, thermal imaging, defense, security, and process control systems. 

G&H offers a range of distributed feedback lasers (DFB) that provide smooth, tunable wavelength control and the narrow spectral width required for precise fiber optics. Applications for these products include spectroscopy and fiber optic communications.

BaySpec introduces Breeze-L™, the world’s smartest palm-held spectrometer in the Short-Wave Infrared (SWIR), with the longest wavelength coverage up to 2500 nm. Featuring proprietary miniaturized optics, the Breeze-L™ with its extended wavelength range of 1350-2500 nm, is highly efficient for maximum sensitivity with ultrafast acquisitions. For the first time, a smart spectrometer delivers close to laboratory performance in a palm-held form.

Zygo’s Nexview™ LS650 is a large format metrology system designed as an inspection tool for automated measurement of injection molding tooling, PCBs, glass panels, and other samples requiring an extended work volume up to 650 x 650 mm. It provides 2D and 3D measurements of a variety of surface features with sub-nanometer vertical precision and sub-micron lateral precision.

Need to integrate laser beam measurements in a system? Gentec-EO can make it happen thanks to a broad range of custom solutions. All products can be customized to meet specific requirements and they can all be used as original equipment manufacturing.

Sensors Unlimited’s 1024-LDH2 is a high-speed 1024-pixel, line scan, InGaAs camera that increases the A-line rate to 91,911 lines per second to enable spectral domain OCT to capture detailed 3-D volumes of the retina, nerve head, and choroid layer in the blink of an eye. For 1.31 μm SD-OCT, diode array-based OCT systems offer superior phase stability for doppler or polarization-sensitive OCT.

PCO introduces the new pco.dicam C4 as a fully integrated 4-channel intensified camera system to exploit the full performance inherent to scientific CMOS sensor technology. The pco.dicam C4 distributes the incident light from a single optical input to multiple modules. These modules are capable of detecting very few photons with nanosecond time resolution.

SPECTROSCOPY NEWS

  • Alluxa’s optical filters, specially designed for the advanced fluorescence spectrometer on the Mars Perseverance Rover, landed safely on Mars, on February 18, 2021.

  • The size of the alpha particle, the nucleus of the helium atom, has been measured more accurately than ever before. Results now indicate a size 1.67824(83) femtometers, which is 4.8 times more precise than previous measurements.

  • 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.
