Compact UV Raman Spectrometer Introduced

Wasatch Photonics is proud to announce the addition of a compact, cost-effective UV Raman spectrometer to its family of modular Raman spectroscopy products. The WP 248 Raman spectrometer expands on the company’s existing range of high sensitivity research and OEM Raman solutions spanning 405 to 1064 nm. Use of UV excitation makes the WP 248 ideal for fluorescence-free Raman spectroscopy, as well as UV resonance Raman (UVRR) to enhance sensitivity and selectivity. Applications range from gas detection and materials analysis to UVRR studies of structure and dynamics in biomolecules such as proteins and nucleic acids. 

The WP 248 is a stand-alone UV Raman spectrometer with free space input and an f/2.0 design for superior signal collection and high throughput detection. It covers a range of 400 to 3200 cm^-1 with 14 cm^-1 resolution, and employs a UV-enhanced CCD for detection. It is designed for use with a compact 248.6 nm NeCu laser, and comes with a triggering cable to synchronise acquisition with the laser. Data collection and spectrometer control is included through the company’s own ENLIGHTEN™ operating software and software development kits for C/C++, C#, Python, LabVIEW, MATLAB, and other languages.

Careful choice of excitation wavelength can also enable UV resonance Raman (UVRR) spectroscopy, which offers 10²-10⁶ signal enhancement for select analytes, or specific subgroups within biomolecules. This combination of enhanced sensitivity and selectivity is invaluable in the study of structure, dynamics, and interactions of proteins and nucleic acids, and has contributed to our understanding of protein folding.  

Wasatch Photonics’ new WP 248 Raman spectrometer offers high sensitivity in a compact footprint for modular UV Raman and UVRR spectroscopy. It covers both the fingerprint and functional range with choice of uncooled and TEC-regulated detector, and can be user-reconfigured with choice of free-space input or integrated lens. Like the company’s existing range of Raman spectrometers for 405, 532, 633, 785, 830, and 1064 nm wavelengths, the WP 248 is available off-the-shelf for applications in research and industry.
