Nanotechnology39FluorometersSingle or multi walled Carbon Nanotubes analyzing toolAbsorption/Raman SpectrometersNS1 NanoSpectralyzerThe NanoSpectralyzer (patent pending) is a unique, easy-to-use spectrometric instrument that is custom designed to give detailed compositional analysis of single-walled carbon nanotube (SWCNT) samples in aqueous suspension. It consists of a compact optical system plus specialized software for apparatus control, data analysis, and results presentation. This system analyzes samples in seconds using the most advanced research !ndings in nanotube spectroscopy. It can be used in automatic mode for routine analyses or with full manual control for sophisticated research$projects.NS2 NanoSpectralyzerIncludes all functions of NS1 plus visible absorption & Raman spectroscopy (532$or$671 nm)NS3 NanospectralyzerIn addition to its core function as a sensitive near-IR "uorometer and absorption spectrometer, the NS3 can be con!gured with any of the following spectral capabilities:????????Visible emission, extended NIR emission, UV absorption, visible absorption, extended NIR absorption, Raman????????Up to 5 excitation lasers (405 to 830 nm)NanoSpectralyzer Model ComparisonNS1NS2NS3Near-IR emission????????????Near-IR absorption????????????Visible absorptionO????????Raman (1 laser)????ORaman (2 lasers)OVisible emissionOExtended NIR emissionOExtended NIR absorptionOUV absorptionOVertical sample scanningOOO = Optional

Spectroscopy40www.lotoriel.co.uk SLM Tunable FiltersSLM Liquid Crystal Modulator ArraysSLM liquid crystal modulator arrays provide independent control of each element in a linear array of 128 or 640 pixels. The single modulator SLM provides adjustment of either phase or amplitude while the dual SLM modulators offer simultaneous control of phase and amplitude. Based on proven industry-leading design it is available in both dual mask and single mask con!gurations for phase control, amplitude control, and phase/amplitude control.????????Exclusive patent for simultaneous phase and amplitude control????????New wavelength ranges????????Improved pixel geometry????????Improved optics alignment and spacing????????Integrated control electronics????????Available in both transmissive and re"ective con!gurationsElectrically Tunable FiltersVariSpec !lters perform like high quality interference !lters with one superior exception - the spectral bandwidth of the light can be controlled electronically. This provides rapid, vibrationless selection of visible (VIS) and near-infrared (NIR) wavelengths. ????????Solid-state design - no moving parts????????Exceptionally compact form factor with large working apertures????????Continuous wavelength tuning ability across hundreds of nanometers????????Rapid, random-access wavelength selection????????High-speed plug-and-play USB interface with Windows DLL support, LabVIEW and Matlab driversVariSpec !lters are used in general research and as OEM components in instruments serving markets such as biomedical imaging, metrology, manufacturing QA/QC and forensics. They are also used in outer space on the International Space Station.Optical Cryostation The Cryostation is a helium-free 3 K - 350 K optical measurement instrument. With speci!c attention to making the researcher more effective, the Cryostation is the most advanced cryogenic optical measurement solution developed.Please see page 14 for more details.
