Products

• LP980: Transient Absorption Spectrometer: Flash photolysis transient absorption spectrometer for following short lived excited states and reaction intermediates. The kinetic configuration measures a decay at a single wavelength; the kinetic and spectral configuration adds an intensified CCD so the whole transient spectrum can be captured at chosen delays. Excitation is a Q-switched Nd:YAG laser with an optional tuneable OPO.
• IR5: FTIR Spectrometer: Fourier transform infrared spectrometer covering 8000 to 350 wavenumbers with a signal to noise ratio of 20,000:1. Integrated desiccants and an electronic dry membrane keep the optics dry without routine purging, and a photoluminescence upgrade adds Fourier transform PL measurement, which is unusual on a benchtop FTIR.
• Fluoracle: Photoluminescence Control and Analysis Software: Control and analysis software for the FLS1000, FS5 and Mini-tau spectrometers. It covers steady state and time resolved acquisition, absolute quantum yield, anisotropy, excitation emission maps and reflection and absorption measurement, together with the data manipulation and export needed to produce publication figures.
• Ramacle: Raman Control and Analysis Software: Control and analysis software for the RM5 and RMS1000 Raman microscopes, covering microscope and measurement setup, 2D and 3D mapping, FastMAP and SurfMAP acquisition and map analysis by peak position, intensity or ratio. A cosmic ray removal wizard and silicon auto-calibration are built in.
• L900: Transient Absorption Control and Analysis Software: Control and analysis software for the LP980 transient absorption spectrometer, handling single and multiple kinetic measurements, time resolved absorption and emission spectra, and delta OD calculation. It also drives the stopped flow accessory and the oscilloscope settings used in kinetic mode.
• FAST: Advanced Fluorescence Lifetime Analysis Software: Advanced analysis package for photoluminescence decay kinetics, going beyond the fitting built into Fluoracle. It is used where decays are complex enough that simple multi-exponential fitting in the acquisition software is not sufficient.
• FLASH: Advanced Transient Absorption Analysis Software: Advanced curve fitting package for transient absorption data, complementary to the L900 acquisition software. It handles the complex kinetic decays produced by flash photolysis experiments where several intermediates overlap in time.
• EPL Series: Picosecond Pulsed Diode Lasers: Picosecond pulsed diode lasers built for time-correlated single photon counting, supplied at fixed wavelengths from 375 nm to 980 nm. Each head includes a built-in spectral filter so no external filtering is needed, and the repetition rate is selectable from 2.5 kHz to 20 MHz. They plug directly into Edinburgh Instruments spectrometers.
• EPLED Series: Picosecond Pulsed LEDs: Pulsed LED sources reaching into the deep ultraviolet from 250 nm, where diode lasers are not available, with sub-nanosecond pulse widths for lifetime measurement. The series runs from 250 nm to 610 nm and shares the housing, trigger interface and mounting of the EPL diode lasers.
• HPL Series: High Repetition Rate and High Power Pulsed Lasers: Picosecond pulsed diode lasers offering higher repetition rate and higher average power than the EPL series, up to 80 MHz. The extra photon flux shortens acquisition on weakly emitting samples, and a high average power option is available on each wavelength.
• VPL Series: Variable Pulse Width Pulsed Lasers: Pulsed diode lasers whose pulse width is selectable from below 70 nanoseconds up to 1 millisecond, for phosphorescence and long lifetime measurements where a picosecond pulse carries too little energy. They also run continuous wave, and pulse width can be defined by an external trigger.
• VPLED Series: Variable Pulse Width Pulsed LEDs: Variable pulse width LED sources covering 255 nm to 1300 nm, a wider span than the diode laser series and reaching further into both the ultraviolet and the near infrared. They are used for phosphorescence and multi channel scaling measurements where a long excitation pulse is needed.
• AGILE: Tunable White Light Source: Wavelength tunable supercontinuum laser giving picosecond pulses across the visible and near infrared with a variable repetition rate, designed for time-correlated single photon counting on the FLS1000. It replaces a set of fixed wavelength diode lasers with one source that can be tuned to the sample.
• PL Series: CO and CO2 Gas Lasers: Continuous wave carbon dioxide and carbon monoxide gas lasers, from the 1 W sealed PL2-S up to the 180 W flowing gas PL6. Line selection ranges from 50 to 90 lines depending on model, and active stabilisation holds frequency to within a few megahertz over ten minutes. They are used in spectroscopy, non-linear optics, LIDAR and interferometry.
• MTL-5: Mini-TEA CO2 Laser: Transversely excited atmospheric pressure carbon dioxide laser delivering pulses of about 50 nanoseconds at up to 100 Hz. It is available untuned for maximum energy or tuned for line selection between 9.2 and 10.8 micrometres, in multimode or TEM00 beam quality.
• FIRL-100: Terahertz Far Infrared Laser: Optically pumped far infrared laser producing terahertz output, tuneable from 40 micrometres to 1.222 millimetres. A CO2 pump laser gives 50 W on its strongest line across 80 accessible lines, and the far infrared cavity converts that to the terahertz region for spectroscopy and physics research.
• 295 and 395: Far Infrared Lasers: Far infrared laser cavities in single cavity (295) and twin cavity (395) form, part of the Edinburgh Instruments FIR series. They are pumped by a CO2 laser to generate far infrared and terahertz output for spectroscopy, non-linear optics and interferometry.
• Xe1: 450 W Xenon Arc Lamp: Ozone free 450 W xenon arc lamp emitting continuous radiation from 230 nm to 2600 nm, used as the steady state excitation source on the FLS1000. The integrated power supply displays lamp voltage and current with an hour meter, and an off-axis ellipsoidal mirror refocuses the emission into the monochromator.
• 150 W Pulsed Xenon Arc Lamp: Xenon arc lamp operated by superimposing a high current pulse on a low current simmer supply, so photon flux during the pulse is far above the steady state level from the same lamp. It gives a broad band light pulse with a flat time profile, which suits measurements that need high pulse energy across a wide spectral range.
• µF1: 5 W Microsecond Flashlamp: Pulsed xenon microsecond flashlamp for the FS5 spectrometer, giving phosphorescence and long lifetime measurement in multi channel scaling mode from below 10 microseconds to 10 seconds. It fits the FS5 only.
• µF2: 60 W Microsecond Flashlamp: Pulsed xenon microsecond flashlamp producing high irradiance optical pulses of a few microseconds at repetition rates up to 100 Hz. The higher energy per pulse compared with the µF1 makes it the source for phosphorescence decay measurements from microseconds to seconds on the FLS1000.
• nF920: Ultrafast Nanosecond Flashlamp: Thyratron triggered all metal pulsed flashlamp filled with hydrogen or nitrogen, producing sub-nanosecond optical pulses for time resolved fluorescence. Because it is a lamp rather than a laser it gives continuous wavelength selection through the excitation monochromator, covering decays from 100 picoseconds to 50 microseconds.
• Filter VUV Light Source: Filter based vacuum ultraviolet excitation accessory consisting of a deuterium lamp, power supply and magnesium fluoride window, providing excitation around 160 nm. Filter options select the excitation band. It is used for scintillator and phosphor work where excitation must be below the range of a normal xenon source.
• Tuneable VUV Light Source: Vacuum ultraviolet excitation system giving continuous wavelength selection from 110 nm upwards, using a continuous wave deuterium source with a specially designed nanosecond flashlamp for lifetime measurement. The path from excitation monochromator to sample is evacuated through a light guide and the sample area is flushed, because air absorbs at these wavelengths.
• Continuous Wave Laser Options: Single wavelength continuous wave lasers supplied for applications such as semiconductor research, directed through a port in the spectrometer onto the sample. They are used where the excitation must be a monochromatic beam of steady intensity rather than a pulse.
• FLS1000: Photoluminescence Spectrometer: Modular research spectrometer for steady state and time-resolved photoluminescence, built around Czerny-Turner monochromators with plug and play triple grating turrets. Sources, detectors and sample chambers are interchangeable, so one instrument covers spectral, fluorescence lifetime and phosphorescence lifetime work. Double monochromators are available where stray light rejection matters.
• FS5: Spectrofluorometer: Compact benchtop spectrofluorometer measuring both absorption and fluorescence in one instrument, with photon counting detection as standard. Sample modules are auto-recognised and swap in seconds, so the instrument moves between cuvettes, solids and plate formats without realignment. It upgrades to near infrared detection, time-resolved measurement, quantum yield and anisotropy.
• LifeSpec II: Fluorescence Lifetime Spectrometer: Dedicated fluorescence lifetime spectrometer using time-correlated single photon counting, with a 90 degree excitation and emission geometry. Temporal dispersion is negligible, which is what allows lifetimes down to 5 picoseconds to be resolved with a microchannel plate detector. A multi channel scaling upgrade extends the range to one second.
• Mini-tau: Fluorescence Lifetime Spectrometer: Compact lifetime spectrometer weighing 5 kg, covering both time-correlated single photon counting and multi channel scaling. A filter wheel with five bandpass filters replaces the emission monochromator, which is what keeps the instrument small and makes it suitable for teaching as well as routine lifetime measurement.
• Plate Readers PR2 and SC-41: Microplate Reader Accessories: Microplate reader accessories for the FLS1000 and FS5 spectrometers, measuring fluorescence spectra and lifetimes from hundreds of wells in one acquisition while keeping photon counting sensitivity. The PR2 is the external module for the FLS1000, the SC-41 the internal module for the FS5.
• MicroPL: Microspectroscopy Upgrade: Upgrade that couples a microscope to an FLS1000 or FS5 spectrometer, so photoluminescence spectra and lifetimes can be taken from a selected point on a sample rather than from a bulk volume. It turns the spectrometer into a combined spectroscopy and microscopy system.
• XS1: X-Ray Radioluminescence Chamber: X-ray sample chamber that connects to an FLS1000 or FS5 by liquid light guide, so scintillator samples can be excited with x-rays and their UV, visible or near infrared emission measured by the spectrometer. Both steady state and pulsed operation are supported, which gives radioluminescence spectra and decay times.
• Customised Systems: Purpose built spectrometer configurations assembled by Edinburgh Instruments where a standard catalogue instrument does not meet the experiment. These are specified with the customer around the required wavelength range, timing regime and sample environment.
• RM5: Confocal Raman Microscope: Fully automated confocal Raman microscope on a 225 mm asymmetric Czerny-Turner spectrograph, with up to three computer selected lasers, matching rejection filters and a five position grating turret. Internal wavelength, Raman shift and sensitivity standards are built in, together with automated laser alignment, so calibration does not depend on the operator.
• RMS1000: Multimodal Confocal Raman Microscope: Research grade multimodal confocal microscope carrying up to five integrated lasers, combining Raman imaging with photoluminescence spectra and fluorescence lifetime imaging in one instrument. The confocal pinhole is fully computer controlled, and a low wavenumber attachment extends coverage down to 5 wavenumbers.
