Where to Buy Raman Spectroscopy Equipment

The Micron laser is a mode-hop free tunable external cavity laser for emission of up to 300 mW. Versions with emission wavelengths between 638 nm and 1700 nm are available.

Headwall's Raman Explorer and Raman Discovery imaging spectrometers are designed for instrument-makers looking for OEM modules suitable for harsh environments (Raman Explorer) or portable instrumentation (Raman Discovery). They both feature Headwall's aberration-corrected, retro-reflective designs with exceptional signal-to-noise and outstanding keystone and smile. Single- and dual-input versions available. Give us a call or send us an email.

For Raman spectroscopy, a wavelength of 532 nm is regularly used, as well as 785 nm (to reduce autofluorescence of the sample). For semiconductor inspection shorter wavelengths of 405 nm, 266 nm, or even 213 nm are commonly used.

Most recent, upcoming time-resolved Raman spectroscopy and microscopy applications (i.e measurements on airplane engine exhausts to optimize the combustion process and reduce fuel consumption) trigger the need for pulsed laser sources operating in the femto- and picosecond regime. This demand is covered by the FemtoFiber laser family, which have already proven its outstanding performance and suitability in various broadband CARS and SRS applications.

Thorlabs manufactures a unique Raman technology employing a coded aperture. The Thorlabs-developed spectrograph unit utilizes a pseudo-Hadamard mask at the spectrograph input instead of a traditional single slit. With an aperture size of 2.3 mm × 3.2 mm, the spatial amplitude modulation mask improves light-throughput, or the system étendue, allowing enough Raman-scattered light to reach the CMOS sensor for room temperature operation and sample excitation with an unfocused laser beam. The spectrograph is designed for 680 nm to 785 nm excitation and an 815 nm to 915 nm detection range. This technology is employed in a modular kit as well as in a portable benchtop device, available with up to two excitation lasers to cover the fingerprint (500–1800 cm⁻¹) and high-frequency regions (2800–3800 cm⁻¹).

The picoEmerald system facilitates Stimulated Raman Scattering (SRS) microscopy for non-invasive label-free imaging. SRS microscopy provides almost background-free imaging contrast. It allows simple spectroscopic identification of the samples’ fingerprint region based on Raman spectra databases. Imaging at high video rates is possible due to very short integration times of the SRS detection module (lock-in amplifier). Switching over to SRS microscopy is relatively straightforward for researchers who already have CARS experience.

Our compact, alignment-free and all-fiber picosecond laser source for CARS microscopy delivers synchronized pump and Stokes pulses from a single fiber end. This air-cooled and turn-key CARS laser source has a great benefit for the user as the fiber delivery eliminates alignment of the spatial and temporal pulse overlap.

Since entering the field of Raman spectroscopy in 2003, Zolix has continued to accumulate technical strength, and continuously updated Raman products. The products have been widely used in materials, geology, biology, chemistry, medicine, food, investigate and other fields. After long-term discussions with customers in different industries, we have launched a new generation of Raman system: Finder 930 is a high-end laser confocal Raman spectrometer with high performance, high stability and high cost performance. Based on the successful experience of previous generations of products, Finder 930 has been fully upgraded in terms of both hardware and software.

CNI offers combined Raman spectroscopy systems. For example, we have portable Raman spectrometers and a micro Raman spectrum measurement system. Available wavelengths are 405 nm, 532 nm, 785 nm and 830 nm.
