  • Handheld Analyzer

Jan 2010
BaySpec Inc.Request Info
BaySpec Inc. has released the Xantus-1 handheld system equipped with a 785-nm laser stabilized for Raman spectroscopy applications. The laser delivers an output power >500 mW and a typical linewidth of 0.2 nm FWHM. The analyzer’s customized spectrograph covers the 500 to 1800 cm–1 range, and its detector is a 1024-element CCD array thermoelectrically cooled to –20 °C. It also features an onboard data processing function and can transmit data to centralized facilities via WiFi networks to offer real-time communication and decision making in mission critical situations. Other applications include incoming materials inspection, mineral identification, food safety evaluation and gemstone authentication.

1. A device designed to convert the energy of incident radiation into another form for the determination of the presence of the radiation. The device may function by electrical, photographic or visual means. 2. A device that provides an electric output that is a useful measure of the radiation that is incident on the device.
1. The range of frequencies or wavelengths over which radiations are absorbed or emitted in a transition between a specific pair of atomic energy levels. The full width is determined between half-power points of the line. 2. In a laser, the range of frequencies over which most of the beam energy is distributed.
Raman spectroscopy
That branch of spectroscopy concerned with Raman spectra and used to provide a means of studying pure rotational, pure vibrational and rotation-vibration energy changes in the ground level of molecules. Raman spectroscopy is dependent on the collision of incident light quanta with the molecule, inducing the molecule to undergo the change.  
An optical instrument for forming the spectrum of a light source and recording it on a film. The dispersing medium may be a prism or a diffraction grating. A concave grating requires no other means to form a sharp image of the slit on the film, but a plane grating or a prism requires auxiliary lenses or concave mirrors to act as image-forming means in addition to the dispersing element. Refracting prisms can be used only in parallel light, so a collimating lens is required before the prism and...
