IR spectroscopy is a useful tool for group chemical species identification of a wide variety of sample materials, particularly for the classification of “organic” chemical materials based upon carbon atoms being present in the molecular structure. Many plastic and polymeric type samples which can be included in the category of organic molecular materials can be classified into particular “family” groupings and it is possible to identify the sample family types both qualitatively and quantitatively by use of the Attenuated Total Reflectance (ATR) technique as an IR measurement.
Hamamatsu have introduced their first high-brightness deuterium (H2D2) light source, with a deuterium lamp that emits UV light at an intensity six times higher than their conventional L2D2 range of lamps.
Oxford Instruments has launched a new cryogen-free (“Cryofree”) optical cryostat, the OptistatDry, which has been designed for low temperature spectroscopy applications.
Specac have introduced the Atlas Autotouch Press range, which has a touch screen display, making operation easier and more user friendly.
Custom SWIR lenses are available from Resolve Optics covering the 900–1700 nm region.
C. Burgess and J.P. Hammond outline the work that has been undertaken to modernise the spectroscopic General Chapters in the United States Pharmacopeia (USP).
Hamamatsu Photonics’ G12430 series of InGaAs photodiode arrays is designed for NIR spectroscopic analysis with three array sizes.
The Shamrock 193i from Andor Technology is a modular spectrograph that uses their Adaptive Focus Technology allowing automated access to the best spectral resolution in any grating, camera or wavelength range combination.
Laser 2000 have introduced the ProMetric Y family of photometers and radiometers for production line testing of flat screens, displays and any type of cosmetic inspection.
Edinburgh Instruments has released a 310-nm picosecond pulsed LED with a sub-800 ps typical pulse width. This is the first of a number of new product releases with this small pulse width and is optimised for time correlated single photon counting (TCSPC).
SpectraPhysis has introduced the InSight DS+, a widely tunable ultrafast laser system.
The 1.3-m focal length McPherson Model 209 spectrometer with new micro-step drive can make wavelength steps as small as 0.1 pm.
Horiba Scientific has launched their Syncerity back-illuminated, deep-cooled CCD camera with an NIR-enhanced 2048 × 70 sensor; it is designed for companies requiring an affordable OEM camera for vis-NIR spectroscopy applications.
Ocean Optics has introduced the STS Developers Kit, which brings together their STS spectrometer, a Raspberry Pi microcomputer, customisable software and wireless capabilities for integrating spectral sensing quickly and easily.
Wavelength References have introduced two fibre-coupled gas flow cells covering the wavelength range from 9 µm.
Shimadzu has launched the new compact and robust “hybrid-bearing” TMP-B300 turbo molecular vacuum pump.
Cyto-Lite, from Mad City Labs and distributed by Elliot Scientific, is a new illumination source that outputs blue, green and red laser light through a single fibre. The key wavelengths are 405 nm, 532 nm and 640 nm with the system providing complete control over each laser line via a single USB interface and the supplied software. The controller and software streamlines the user interface and allows the characteristics of each laser line to be independently controlled in constant current feedback or constant optical power feedback modes. The on-board DDS sine wave generator and internal 16-bit DAC allow for the modulation and amplitude of each laser line waveform. Low noise operation is achieved by three independent linear regulator power supplies and filtering on each laser line further minimises electronic noise. Robust and safe operation is achieved through multiple layers of laser line protection. Watchdog circuitry maintains stable power supply operation and each laser line has overcurrent protection circuitry.
The new Spirit from Spectra Physics is a compact, industrial grade, ultrafast amplifier with software-adjustable repetition rates up to 1 MHz. The ultrafast laser provides high average power and fully-automated adjustability over a wide range of repetition rates from 50 kHz to 1 MHz. Featuring a rugged one-box design, the laser delivers ultrashort 400 fs pulse widths with high energy of 20 µJ per pulse.
Laser Components has introduced the LabSource series of benchtop laser sources manufactured by PD-LD with Volume Bragg Grating stabilised laser diodes to its list of products. Two models are available, the LS-1 with a single volume Bragg grating laser diode and LS-2 featuring two stabilised sources. The dual wavelength functionality of the LS-2 enables use in a variety of tasks including SERDS, which involves two Raman spectra formed from closely matching but different excitation wavelengths allowing the offset of background fluorescence, resulting in improvement in the identification and measurement of organic and biological samples and in security industries where fluorescence is widespread.
RM21 is a precision aligned microscope platform designed for improved user accessibility by Mad City Labs and distributed by Elliot Scientific. It offers microscopists the opportunity to develop flexible configuration instruments with ease. It is precision manufactured to allow easy alignment of microscopy and optical components within its three-dimensional space and all posts and fixturing points are referenced to a known datum. With a robust design, precision manufacturing and assembly, it is a suitable platform for a range of microscopy applications including super resolution microscopy, fluorescence microscopy and TIRF. It includes a precision platform and an axial motorised Z-axis suitable for lens positioning. An encoder option is also available.
