Products

• inVia confocal Raman microscope — Renishaw: A research grade confocal Raman microscope that pairs a research microscope with a high performance Raman spectrometer. It records point spectra and chemical images from solids, liquids and thin films, and is supplied in three models: inVia Basis, inVia Reflex and inVia Qontor.
• inVia Qontor confocal Raman microscope — Renishaw: The flagship model of the inVia range. It adds LiveTrack focus tracking so that spectra and topography can be collected in real time from uneven, curved or rough surfaces without pre-scanning, together with full automation, internal calibration sources and a performance health check.
• inVia InSpect confocal Raman microscope — Renishaw: A version of the inVia microscope set up for forensic laboratories. It identifies crystalline powders, ceramic shards, glass fragments, fibres and inks without contact and without destroying the sample, and offers brightfield, darkfield and polarisation contrast for particle work.
• Strada Intelligent Raman Microscope — Renishaw: A high performance Raman microscope built for industrial laboratories, with full automation and workflow driven Raman Workspace software. It analyses sub-micrometre particles, weak scatterers, dilute solutions and trace contaminants, and supports 21 CFR Part 11 compliance.
• Time-resolved Raman spectroscopy (TRRS) — Renishaw: A configuration for the inVia confocal Raman microscope that uses a pulsed laser and an ultra-fast detector to separate Raman scattered photons from fluorescence by arrival time. It recovers usable spectra from strongly fluorescent samples and from samples at very high temperatures.
• Virsa Raman analyser — Renishaw: A transportable Raman system with fibre optic coupled probes for microscopic and bulk analysis outside the laboratory. Automatic focus tracking lets it follow irregular, moving or changing samples in real time, and live white light viewing is used to target the measurement point.
• Virsa Raman analyser for PAT bioprocess monitoring — Renishaw: The Virsa analyser supplied with dedicated optics for process analytical technology in biopharmaceutical production. It monitors metabolite concentrations in a bioreactor continuously, so upstream and downstream processes can be controlled without relying on offline HPLC checks.
• RA802 Pharmaceutical analyser — Renishaw: A dedicated Raman imaging system for pharmaceutical formulation work. Using StreamLine rapid imaging and LiveTrack focus tracking it builds a chemical image of a tablet surface in as little as five minutes, showing how each component is distributed through the sample.
• RA816 Biological Analyser — Renishaw: A compact benchtop Raman imaging system for biological and clinical research. It maps the distribution and amount of biochemical species in tissue biopsies, tissue sections and biofluids with little or no sample preparation and without stains, tags or contrast agents.
• RM5: Confocal Raman Microscope — Edinburgh Instruments: 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 — Edinburgh Instruments: 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.
• witec360 Raman Imaging Microscope — Oxford Instruments: Oxford Instruments publish the witec360 as the new benchmark for Raman imaging and correlative microscopy, aimed at academic and industrial researchers who need comprehensive analysis at the nanoscale. The core system is broadband from 350 to 1100 nm, with options extending from 266 nm in the UV to 1064 nm in the NIR, and spectral resolution reaches 0.1 cm-1 at 633 nm excitation. Lateral resolution is below 300 nm and depth resolution below 950 nm depending on excitation wavelength, with acquisition below 1 ms per spectrum. Spectrometers are offered at 300 mm or 600 mm focal length carrying up to six gratings, the objective turret holds up to six objectives, and sample positioning travel ranges run from 25 mm by 25 mm to 350 mm by 300 mm.
• witec360 access Entry-level Raman Microscope — Oxford Instruments: A micro-Raman microscope for single spot analysis and mapping, engineered by Oxford Instruments for budget conscious customers who still hold high demands on instrument performance. It is built to be upgraded, so a laboratory can start at entry level and extend the system later.
• witec360 Semiconductor Edition — Oxford Instruments: A high end confocal Raman and photoluminescence microscope configured specifically for chemical imaging of semiconducting materials. Wafers up to 12 inch, that is 300 mm, are handled on a 300 by 350 mm scanning stage, and peak shifts below 0.01 cm-1 can be detected. Vibration damping, TrueSurface active focus stabilisation and fully automated microscope control are included, and various laser wavelengths are available.
• cryoRaman Cryogenic Raman Imaging Microscope — Oxford Instruments: The performance and modularity of the witec360 Raman microscopes combined with advanced cryostat and nanopositioner technology, which puts experiments down to 1.8 K in high magnetic fields within easy reach. Solenoid magnets up to 12 T are available, as are vector magnets, using low vibration closed cycle attoDRY cryostats. Excitation runs from the visible to the NIR through cryogenic compatible high numerical aperture objectives, with polarisation control on both excitation and detection, and options for time correlated single photon counting and low wavenumber Raman detection.
• RISE Raman-SEM Microscope — Oxford Instruments: Published by Oxford Instruments as the world's first fully integrated Raman imaging and scanning electron microscope, bringing every feature of a stand-alone SEM and of the confocal witec360 Raman microscope into one instrument. Switching between the Raman and SEM measurement positions is quick and the sample transfer between them is automated, so results correlate and images overlay directly. Diffraction limited lateral resolution is 200 to 300 nm, three dimensional images and depth profiles are supported, and an ultra-fast Raman imaging option brings integration time down to 0.76 ms per spectrum. A RISE-EDS configuration adds Raman-SEM-EDS in the same instrument.
• alphaCART Mobile Raman System — Oxford Instruments: A mobile confocal Raman system for the applications where the laboratory has to travel to the sample. The Raman probe is positioned flexibly in front of bulky, immovable or precious objects that cannot be transported to a microscope or that will not fit under one. The system ships in a flight case of roughly 100 by 60 by 60 cm, covers about 90 to 3500 cm-1 depending on excitation wavelength, and is offered with 532 nm, 633 nm or 785 nm lasers at output powers from 30 mW to more than 200 mW. Spatial resolution is diffraction limited and the system runs under Microsoft Windows 11.
• inVia Basis confocal Raman microscope — Renishaw: inVia Basis is the entry level model in Renishaw's inVia confocal Raman microscope range, which also holds the inVia Reflex and the flagship inVia Qontor. Like the other models it couples a research grade microscope to a high performance Raman spectrometer on a custom honeycomb baseplate that is stable enough that an optical or anti-vibration table is not normally required. On the Basis model, automated measurement queuing, automated Raman calibration correction, laser auto-align and Raman signal auto-align are included, and stereo viewing through binocular eyepieces is an option. Software microscope control, automatic white light and Raman switching, the internal neon wavelength calibration source and LiveTrack focus tracking are not available on this model.
• inVia Reflex confocal Raman microscope — Renishaw: inVia Reflex sits between the entry level inVia Basis and the fully automated inVia Qontor in Renishaw's confocal Raman microscope range. On top of the shared inVia spectrometer and research grade microscope it adds software microscope control, automatic switching between white light and Raman, automatic saving of the white light image with the data, combined white light and laser video viewing, and memorised automatic post collection viewing. An internal neon wavelength calibration source, internal reference standards for auto-calibration and a performance health check are included as well. LiveTrack automated focus tracking stays exclusive to the inVia Qontor model.
• THz-Raman Integrated Systems — Coherent: THz-Raman Integrated Systems are turnkey Raman platforms that record the low frequency and fingerprint regions in one measurement. The TR-WPS is a microplate reader with intra-well mapping and the TR-WALDO adds upright and inverted microscopy with translation stages.
• THz-Raman Modular Systems — Coherent: THz-Raman Modular Systems upgrade an existing spectrometer so it can collect the low frequency Raman region from about 5 to 150 cm-1. Each module includes the laser and the filters needed to produce a clean spectrum to within about 5 cm-1, with a fibre optic output to the spectrometer.
