Wasatch Photonics XS Series Raman Spectrometers
Ultrasensitive Raman Spectrometer in the Palm of Your Hand
With the introduction of the ultracompact XS Series Raman spectrometers, Wasatch Photonics is poised to revolutionise field-deployable measurements. This all-in-one device integrates the spectrometer, laser and battery into an ultra-compact design whilst maintaining exceptional sensitivity, thanks to its low f-number optical bench and transmission diffraction grating. The uncooled CMOS detector ensures low power consumption, making it an ideal solution for cost-effective, high-volume applications without compromising performance. The Raman XS is available with a choice of Raman excitation wavelengths, all covering the fingerprint region for reliable chemical identification.
Compact, Field-Deployable Raman Spectrometer – Without Compromise
The XS Series Raman Spectrometer was designed to fulfil Wasatch’s mission to ‘Bring Raman to Life’. It is small enough to be used in the back of an ambulance or by field inspectors, sensitive and stable enough to give accurate & dependable answers, and cost-effective enough to open up new markets and use cases for Raman. Consistent with this mission, we are offering both an XS model for point sampling of materials (point-and-shoot, liquids, and powders), and an XSB model for line sampling of biomaterials (SERS substrates, lateral flow assays, inhomogeneous samples).
Key Features
- High throughput optical bench design based on patented VPH diffraction gratings
- Low f#, highly sensitive optical design with low power, uncooled CMOS sensor
- Integrated TEC controlled single mode laser & probe / sampling optics
- 633, 785, or 830 nm excitation (XS) or novel 785 nm line-illumination sampling (XSB)
- Raman fingerprint range & resolution suitable for robust identification and classification
- High shot-to-shot signal reproducibility & wavenumber stability
- Accessories (XS & XSB): point and shoot, cuvette/vial holder, polystyrene calibration standard
- Line-illumination accessories available for SERS substrates & LFA cassettes (XSB)
- Power and communications over USB-C using ENLIGHTEN™ operating software
Wasatch Photonics WP Raman XS Series
The high-sensitivity, f/1.3 optical bench comes with your choice of Raman excitation wavelengths, all covering the fingerprint region for reliable chemical identification. Use of an uncooled CMOS detector ensures low power draw, whether operated on battery, or over USB-C for combined power and communications. All units may be run via USB-C using the ENLIGHTEN operating software. The free space output features an accessory interface with laser interlock, for which several accessories are available: point and shoot, cuvette/vial holder, and polystyrene calibration standard. In addition, the associated accessory plate uses an SM05 thread, facilitating the interface of custom accessories.
