Raman

Headwall's Raman imaging instruments are exceptionally small, light, and rugged. Raman spectroscopy is typically used to observe vibrational, rotational, and other low-frequency modes in a system. It relies on inelastic (‘Raman’) scattering of monochromatic light from a laser in the visible, near infrared, or near ultraviolet range. The laser light interacts with molecular vibrations, resulting in the energy of the laser photons being shifted up or down. This shift in energy gives researchers information useful in various fields of chemistry and medicine, since vibrational information is specific to the chemical bonds and symmetry of molecules.

Headwall has developed two product families--Raman Explorer™ and Raman Discovery™—that are best in class for a wide range of high-performance applications. Raman Explorer, designed for applications ranging from deep sea to deep space, provides high optical efficiency and throughput with a minimum of optical noise. High spatial resolution comes from a tall entrance slit that affords optimized signal collection with minimal image distortion and channel crosstalk. A very short focal length with f/2.4 optical throughput permits the instrument to be very compact. Explorer also has the ability to process separate calibration and radiometric reference channels.

Raman Discovery is an affordable, hand-held solution for Raman applications where multi-channel Raman imaging measurements are key differentiators. It is a very portable unit designed for harsh, mission-critical environments. High optical efficiency, high spectral and spatial resolution, and a large entrance aperture with minimal image distortion are key advantages of Raman Discovery.
