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 — Edinburgh Instruments: Compact benchtop spectrofluorometer measuring both absorption and fluorescence in one instrument, with photon counting detection as standard.

• iKon Slow-Scan Large CCD Cameras — Oxford Instruments: The iKon slow scan CCD series applies thermoelectric cooling to -100 °C for very low noise, with back-illuminated photon collection across a broad spectral range and wide dynamic range. Its low maintenance design suits long exposure, low light work in astronomy and weak luminescence detection, and it is robust enough for remote observatories. A Fast Kinetics mode can also capture bursts of data with microsecond dynamics for quantum gas absorption experiments. Two models are offered, the 2048 x 2048 iKon-L 936 and the 1024 x 1024 iKon-M 934, with standard silicon and deep depletion sensor options for enhanced near infrared response.
• sCMOS Camera Series — Oxford Instruments: Scientific CMOS brings together a set of performance characteristics that Andor describes as a breakthrough for high fidelity, quantitative scientific measurement. Large field of view and high resolution come from multi-megapixel sensors, and none of that costs read noise, dynamic range or frame rate. Five platforms make up the series, among them two workhorse models: ZL41 Cell for life science researchers and ZL41 Wave for physical science researchers.
• Intensified CCD and sCMOS Cameras — Oxford Instruments: Andor's intensified camera series draws on CCD and sCMOS sensors together with gated image intensifier technology, combining rapid acquisition rates with ultra-high sensitivity down to single photon. Four platforms are offered: the iStar 320T for high resolution, nanosecond scale time-resolved spectroscopy, the 1024 x 1024 iStar 334T for time-resolved imaging, the high resolution iStar 340T for spectroscopy, and the USB 3.0 iStar sCMOS. Andor states the iStar sCMOS reaches frame rates at least 50% faster than competing CCD or interline platforms at equivalent pixel matrix size, while keeping intrinsically low noise.

The CCD version comes in 1024 x 256 and 2048 x 512 formats with 26 or 13.5 µm pixels, reaching 1,612 spectra per second, while the EMCCD version uses 1600 x 200 and 1600 x 400 formats with 16 µm pixels and reaches 1,515 spectra per second. Both cool to -100 °C with UltraVac and reach 95% peak quantum efficiency. A fast kinetics mode with microsecond resolution is available for broadband spectra.
• CCD, sCMOS & EMCCD Cameras for X-ray and EUV — Oxford Instruments: Andor groups its high energy detection cameras into a single portfolio spanning CCD, sCMOS and EMCCD sensors for table-top laboratory and beamline experiments.

Three coupling approaches are covered: open front direct detection with UltraVac, fibre optic coupled indirect detection, and lens coupled indirect detection. The newest platform is the Marana-X back-illuminated sCMOS for direct X-ray detection.
• NIR SWIR Cameras — Oxford Instruments: Andor's C-RED series gathers InGaAs based cameras built for quantitative scientific measurement in the NIR II and SWIR imaging window. High sensitivity is matched to high speed and wide dynamic range across a wide field of view, so both fast processes and slow ones running to several minutes of exposure can be captured. Three models make up the family: the C-RED 2 for high speed low noise work, the compact temperature stabilised C-RED 2 Lite, and the C-RED 2 ER extended range versions reaching 1.9 µm and 2.2 µm.
• Kymera 193i Spectrograph — Oxford Instruments: Designed around research-grade performance, versatility and ease of use, the Kymera 193i uses intelligent motorised adaptive focusing to reach the best spectral resolution in any configuration with high repeatability. Its 193 mm focal length and F/3.6 aperture, paired with Andor's ultra-sensitive UV-NIR and SWIR detectors, give strong photon collection efficiency for low light micro-fluorescence and Raman work as well as routine spectral acquisition. An indexed dual-grating turret with eXpressID RFID recognition, dual detector outputs and an astigmatism-corrected toroidal optical design make the platform highly configurable. Dedicated micro-spectroscopy interfaces, including a modular cage system, allow direct integration with microscopes.
• Kymera 328i Spectrograph — Oxford Instruments: The Kymera 328i is a highly modular third-metre spectrograph with patented Adaptive Focus, a quadruple on-axis grating turret and TruRes technology for enhanced spectral resolution. Its motorised Adaptive Focus automatically reaches the best optical performance for any grating, camera or wavelength range, while TruRes delivers resolution gains exceeding 30% without changing grating or applying mathematical post-processing. The 328 mm focal length and F/4.1 aperture cover luminescence and photoluminescence spectroscopy through to higher resolution Raman and plasma studies. A robust on-axis wavelength drive gives single-grating and grating-to-grating centre wavelength repeatability down to 4 and 10 pm respectively.
• Shamrock 500i Spectrograph — Oxford Instruments: Built on a Czerny-Turner optical design, the Shamrock 500i imaging spectrometer is optimised for multi-track spectroscopy. It is supplied pre-aligned and pre-calibrated as a camera and spectrometer detection solution so it drops into an existing set-up, with a spectroscopy-dedicated software interface giving real time control of detectors and spectrometer together. Optimised toroidal optics correct image astigmatism for high density multi-track work, and the motorised indexed triple grating turret can be upgraded in the field.
• Shamrock 750 Spectrograph — Oxford Instruments: The Shamrock 750 offers the highest resolution in the Shamrock family and also handles multi-track work well. Its rugged Czerny-Turner platform is supported by a wide range of light coupling accessories and gratings, and pairs with Andor's CCD, electron multiplying CCD, InGaAs and intensified CCD cameras. Systems are supplied pre-aligned and factory calibrated, and Solis spectroscopy software provides a single interface for spectrograph, detector and motorised accessory control. A multi-track enhanced option optimises the system for low crosstalk, high density multi-leg fibre signal acquisition.
• Mechelle 5000 Spectrograph — Oxford Instruments: The Mechelle ME5000 echelle spectrograph records a wide wavelength range from 200 to 975 nm simultaneously in a single acquisition. It has no moving components and is available in a pre-aligned detector and spectrometer format, with a patented optical design based on the echelle grating principle that gives extremely low crosstalk and high resolution. Automatic temperature correction compensates for the change in prism refractive index with temperature, and nitrogen purging maximises throughput in the ultraviolet. Andor Solis software extracts a fully wavelength calibrated spectrum from the complex echelle image and can label peaks against the NIST table.
• Luminosa PDA-23 Add-On — PicoQuant: The PDA-23 add-on equips the Luminosa confocal microscope with a cooled 23-pixel SPAD array for confocal time-resolved detection, combining the higher resolution of image scanning microscopy with quantitative FLIM. Pixel reassignment raises resolution by about 30%, taking 485 nm excitation down to 155 nm FWHM, and deconvolution takes that further to 120 nm FWHM. Computational sectioning improves contrast by rejecting out of focus light, and every pixel of the array is time tagged, with dual-channel acquisition available simultaneously through pulsed interleaved excitation. Integrated in Luminosa, the detector keeps alignment stable and pairs with the MultiHarp 160 multichannel time tagging and TCSPC unit, with analysis handled in NovaISM.
• MicroTime 200 STED Add-On — PicoQuant: This open STED add-on extends the MicroTime 200 to super-resolution imaging with time-resolved contrast, resolving nanoscale structures below 50 nm that confocal images cannot separate. A stable donut shaped depletion beam is produced by an EASYDOnut phase plate, which avoids complex alignment, and gSTED time gating isolates late photons for better resolution and sensitivity. Triple-species STED imaging is possible using fluorescence pattern matching for accurate multicolour co-localisation, and the reduced observation volume benefits STED-FCS by allowing diffusion measurements at higher concentrations. Full compatibility with the MicroTime 200 is retained, and the complete STED workflow including time gating and multi-species pattern matching runs in SymPhoTime 64.
