WP 785 XL Raman Spectrometer

Capture your most elusive Raman signals with this compact, powerhouse spectrometer designed for the unique needs of research Raman. We’ve built it around our high efficiency VPH transmission gratings and diffraction limited optics, and stacked it with flexible configuration options to address a wide variety of range, resolution, sensitivity, and sample interface needs, making even your most novel & demanding Raman measurements a reality.

Make it a powerful, fully modular research Raman setup:
• Delivered off-the-shelf with an ultra-cooled Andor iDus 416 camera; optical bench design is also compatible with other Andor camera models upon request, or available without camera
• Add a 785 nm laser and our unique user-configurable probe and sampling chamber
• OR add an off-the-shelf optical cage system for maximum flexibility in your sampling optics
• Collect automated optical dark measurements easily using the internal shutter & TTL control
• Control camera via chosen camera vendor software to access novel multi-channel and stacked-fiber measurement options

*Start and end wavenumber may be customized, but total range is fixed. Contact us for options.

Note: Specifications are subject to change based on available components & manufacturing data.

By popular request, we’ve designed one of our compact, high-throughput optical benches for use with an ultra-cooled scientific camera, giving you the best of both worlds for the most challenging Raman measurements in your research. Every Raman scattered photon is treated as precious by our high-efficiency optics and patented VPH transmission gratings, with spectrometer configuration options that let you balance input aperture and range with resolution. Compatibility with ultra-cooled scientific cameras enables novel multi-channel and stacked-fiber measurements, while our user-interchangeable input coupling (-IC) makes unique sampling geometries & slit changes a breeze.

One of the significant advantages of our WP Raman XL-Series is its modular input interface, allowing it to easily integrate into both new and existing setups. This is reflected in our configurable input aperture (f/1.5 or f/2.0), as well as our interchangeable coupling (-IC) system that enables selection of both slit size and input type. The WP Raman XL-Series can also be interfaced directly with off-the-shelf 30 mm optical cage systems, accommodating 25 mm (1″) diameter optics, as shown at left. An optical cage system uses four rigid steel rods to mount optical components along a common optical axis, allowing the user to continuously modify the system’s design by adding additional components, such as optical mounts and angular brackets.

No matter where your research takes you, we’ve designed an optical bench with the flexibility to get you there. Contact us to discuss your needs.

The pattern of peaks in a Raman spectrum is unique to the sample, providing a fingerprint which can be used to identify or analyze the material. The ‘fingerprint’ region up to 1500 cm^-1 is often enough to confirm identity, while the extended ‘functional’ region out to 3600 cm^-1 includes bands for additional, functional groups in a molecule. In addition to our standard models, we can design custom range spectrometers for OEMs. See below for common Raman spectral bands.

Need something slightly different? We offer a more lightweight line of spectrometers with TEC-cooled CCD array detectors for reduced cost, and can offer expert advice on which may be the right match for your application. Consider the option below, or explore our full family of Raman products.

Choosing the right Raman wavelength for your application is a question of balancing sensitivity and selectivity. Although shorter wavelengths deliver the strongest Raman signal, fluorescence background can degrade signal-to-noise ratio (SNR) if the wrong wavelength is used. That’s why we offer Raman spectrometers for wavelengths from 248-1064 nm, matching your specific needs and sample type to the best wavelength for the application. Explore our alternate wavelengths below. Still unsure of what you need? Contact us for a personal consultation or sample testing.
