SpectraPro HRE

For General Spectroscopy Applications and
Laser-Induced Breakdown Spectroscopy
TRENTON, N.J., Nov. 7 -- Princeton Instruments/Acton (PI/Acton), a manufacturer of high-performance, camera and spectrograph-based solutions for the imaging, x-ray, spectroscopy and security markets, announces the release of the new SpectraPro HRE high-resolution echelle spectrograph. The company says the system represents a unique approach to spectrograph design, which is ideally suited for use with PI/Acton’s CCD and ICCD (intensified CCD) camera systems. The SpectraPro HRE achieves high spectral resolution over the entire wavelength range of the camera without any moving parts and can be used for general spectroscopy applications and laser-induced breakdown spectroscopy.

The SpectraPro HRE uses the echelle grating principle, where multiple orders of diffraction are separated by a cross-dispersive prism before they are imaged onto a CCD. The instrument can sample wavelengths ranging from 190-1050 nm continuously without any moving parts. “A large spectral range with picometer resolution can now be obtained without the need for scanning the grating,” said Senior Product Manager Marc D. Neglia. “The HRE can even be configured to image down to 150 nm when required.”

Interchangeable wavelength dispersive elements offer the option of choosing the best resolution and wavelength for any application. Without having to purchase a new spectrograph, the element can be changed to suit a different resolution or wavelength coverage requirement. A wide selection of input apertures can be selected, from as small as 10 µm to as large as 100 µm.

The SpectraPro HRE spectrograph is controlled by WinSpec software, with which the user can choose the desired wavelength interval per point in the spectrum. Example calibration images can be generated to ease the peak selection and calibration can be achieved by using two points on the image of known spectral lines. Once calibrated, spectra can be obtained in real time as the spectral orders are linked, linearized and plotted using the WinSpec snap-in.
