Why Raman? and Why Now? A Primer on Raman Spectroscopy The Raman effect occurs when light impinges upon a molecule and interacts with the electron cloud that binds that molecule. While most of the incident light is scattered with its wavelength unchanged (i.e., elastically scattered), a small fraction (on the order of 10-6 ) of the light is inelastically scattered and exits with longer wavelength and simultaneously promote the molecule into a more energetic vibrational state. An even smaller fraction of the light picks up energy from the molecule and leaves with a shorter wavelength. This effect was named after one of its discoverers, Sir C. V. Raman, who, in 1928, accomplished his observation with sunlight and filters. A change in the molecular polarizability or deformation of the electron cloud with respect to the vibrational coordinate is required for the molecule to exhibit the Raman effect. The amount of the polarizability change will determine the Raman scattering intensity, whereas the shift in wavelength (called the Raman shift) is equal to the vibrational level that is involved. When the shift is to longer wavelength it is called the Stokes shift, and when it is to shorter wavelength it is called the anti- Stokes shift. The location and intensity of the Raman lines are determined by the underlining molecular structure and are unique to the molecule and its environment, thus the Raman spectrum bears a molecular spectral finger print. For Raman spectroscopy both excitation and detection are achieved in the visible or near-infrared range, but the obtained spectral information is in the infrared range (difference between excitation and detection). Detection of light in the visible/near infrared is generally much easier than in the infrared since it is less susceptible to thermal noise. Raman spectroscopy is a powerful analytical technique owning to its nondestructive nature and simplicity in sample preparation and handling. However, its full potential could not be reached until now. The reasons may be traced back to Sir C. V. Raman s original observations made in 1928; in his Communications to Nature he commented that the effect s excessive feebleness and the need for very powerful illumination. Lasers, invented in the 1960 s, certainly qualified as powerful illumination sources. However, for a long time lasers were bulky, expensive, and required experts to operate. A laser Raman spectrometer from mid-1980s Sensitive detectors and other optical components such as line-ruled gratings were also scarce and expensive. Thus Raman spectrometers were reserved for sophisticated scientific research and not accessible for routine analytical applications. Why Now? In the late 1990 s the buildup of the optical telecommunications infrastructure brought down price barriers for many lasers while reducing their physical dimensions. Holographic optical components are also much more accessible than before. Together with compact yet powerful computers/microprocessors high performance Raman spectrometers can be made in portable, even handheld, form factors at a fraction of the cost of traditional research instruments today. The time for Raman is NOW. A handheld Raman spectrometer from BaySpec in 2009 성경포토닉스 l 042) 867-2227 2 www.skphotonics.com
The BaySpec Advantage Volume Phase Grating (VPG ) Central to any dispersive spectrometer is the grating, the dispersive element. Transmission VPGs offer generally higher efficiencies than traditional reflective gratings. For low signal applications this is a significant performance edge. BaySpec s Raman spectrometers are equipped with VPGs so that they have higher optical throughput than similar products on the market. These VPGs are designed and manufactured on site at BaySpec. The spectral coverage of the spectrometers is solely dictated by customers needs and not limited by the availability of gratings from third party vendors. VPG s manufactured at BaySpec Schematic Diagram of a NIR Dispersive Spectrometer based on a Transmissive Holographic Volume Phase Grating (VPG ) Right Detector for the Right Job BaySpec offers a complete line of array detectors in the visible and near infrared that are sensitive to 1700 nm, 2200 nm, or 2500 nm. Noise from dark currents is a challenging issue for NIR detectors, especially when the spectral range is extended to mid- IR. To ensure exceptional signal to noise ratio in every spectral range, BaySpec s detectors run either athermally, or thermoelectrically cooled to 20 C. For even more demanding applications the detector array can be cooled to 55 C. 성경포토닉스 l 042) 867-2227 3 www.skphotonics.com
