Because of the system’s series of comprehensive software wizards, even novice users of the fully automated device can perform complex measurements, such as fluorescence decays and time-resolved anisotropy studies, in a short time. Advanced users have full access to all instrument capabilities through a point-and-click interface or integrated scripting language. The spectrometer supports both time-correlated single-photon counting and multichannel scaling data acquisition, and it covers lifetime ranges from picoseconds to milliseconds. With the addition of an optional monochromator, the FluoTime 250 can measure time-resolved emission spectra.

That wide tuning range and the source’s high resolution and sensitivity are achieved with an optical parametric oscillator and difference-frequency generation architecture. The combination of 300 cm−1 broadband and 20 cm−1 narrowband emission makes the Carmina suitable for the two complementary nanoscale IR techniques: scattering near-field scanning optical microscopy and atomic force microscope IR spectroscopy. A pulsed mode consisting of a burst with a 50% duty cycle is included for AFM-IR applications. The light source is suitable for use in near-field imaging and spectroscopy of organic and inorganic samples.

The laminar groove profile of the gratings helps keep a high-energy spectrum clean and more easily interpretable, especially at short wavelengths. The gratings are designed for grazing-incidence optical beams. A shallow 1.5-degree grazing-incidence angle improves efficiency for high-energy photons at wavelengths below 5 nm. The model 251MX is optimized for high-energy photons, including soft x ray and extreme UV (EUV). According to the company, it is easy to use and delivers reliable performance for water window imaging, high-harmonic-generation laser spectroscopy, x-ray plasma diagnostics, EUV lithography, optical characterization, metrology, and calibration.

With its quantum cascade laser technology, rapid scanning optics, and intuitive Agilent Clarity software, the system provides fast, high-definition (HD) chemical imaging and accurate analysis of the composition of tablets, laminates, tissues, polymers, and fibers. The 8700 LDIR produces images free from laser coherence artifacts and provides HD images of large areas. Its automated operation, with no need for liquid nitrogen, makes HD chemical imaging accessible to operators at all levels of expertise in academic and commercial facilities.

The new DSPEC 50A and DSPEC 502A models include high-precision coincidence timing to simplify Compton suppression and cosmic-veto system configurations. According to the company, the coincidence-timing functions are simple to operate and offer high performance. The spectrometers feature 64 K analog-to-digital conversion gain for superior low-energy peak shape in broad-energy-range applications. Web-based interfaces permit custom application development and allow use of the DSPEC 50A and DSPEC 502A on computers running any operating system.

Lumetta is designed to optimally gather light from most fibers and high-angle scattering phenomena. The imaging spectrograph can perform such advanced techniques as multitrack spectroscopy and fast hyperspectral imaging. With multitrack spectroscopy, it can measure multiple independent spectral channels, which either improves throughput for similar measurements on different samples or allows simultaneous measurement of different but complementary spectra, such as photoluminescence and absorbance, from the same sample. Lumetta’s CCD, which is deep-cooled to −50 °C, and its low-noise 16-bit electronics deliver high sensitivity for low-light applications.

Marana features 95% quantum efficiency, vacuum cooling down to −45 °C, and high sCMOS sensitivity. According to Andor, it is the largest field-of-view sCMOS commercially available. Marana combines a 4.2 MP array format with 11 µm pixels resulting in a large, 32 mm sensor diagonal. Its 48 fps rate makes the camera useful for high-time-resolution astrophysics—for example, in pulsar studies—and for dynamic quantum research experiments. Integrated with Andor’s spectrograph range, Marana offers fast spectroscopy modes that can monitor rapid kinetic processes and reactions at thousands of spectra/s and allow for fast multifiber hyperspectral imaging applications.

The precision EUV mirrors feature nearly ideal reflectivity at 13.5 nm. They are offered in two versions: 5° angle of incidence (AOI) mirrors suitable for use with unpolarized beams and 45° AOI for steering s-polarized beams. Their superior thermal stability results from a coating deposited on a super-polished single-crystal silicon substrate. The metal–semiconductor coating includes a molybdenum–silicon multilayer with a Si top layer. The mirrors have a surface flatness of λ/10 at 632.8 nm and 6.35 mm thickness. They exhibit a surface roughness less than 3 Å and greatly reduce incident light scatter.
