Utilizes Exclusive Princeton Instruments Technology Developments

Princeton Instruments, a worldrenowned manufacturer of scientific cameras and spectroscopy equipment, is pleased to introduce the SpectraPro HRS-750, a new 750 mm focal length spectrograph and scanning monochromator that features an astigmatismcorrected optical design, a mechanical scanning range of 0 to 1500 nm, as well as exceptional resolution of 0.05 nm or better. This versatile instrument is the latest addition to Princeton Instruments’ popular SpectraPro HRS series of spectrographs and monochromators, which also includes the SpectraPro HRS-300 and the SpectraPro HRS-500.

New technology built into the HRS-750 includes Princeton Instruments’ exclusive spectral deconvolution technology, ResXtreme, which is provided with every SpectraPro HRS spectrometer. ResXtreme improves the spectral resolution, peak intensities, and consistency across the 2D focal plane by as much as 60%, all with the push of a button.

“In addition to ResXtreme, the SpectraPro HRS-750 configuration option of two exit and two entrance ports gives researchers tremendous experimental versatility that no other commercially available scientific-grade spectrometer can match,” observes Shixin Sun, spectroscopy product manager at Princeton Instruments. “The exit ports have a full 14 mm x 30 mm focal plane, which enables the mounting and operation of two array detectors [e.g., any of Princeton Instruments’ CCD, EMCCD, ICCD, sCMOS, or InGaAs sensors] or allows the SpectraPro HRS-750 to operate as both a monochromator and a spectrograph.”

The SpectraPro HRS-750 can also take full advantage of Princeton instruments’ patented IntelliCal® wavelength and intensity calibration system. IntelliCal’s push-button wavelength calibration routinely achieves up to 10x more accurate wavelength calibration than conventional calibration methods, while its fast and easy intensity calibration removes unwanted instrument responses that can degrade spectral data.

Every SpectraPro HRS-750 can utilize as many as three interchangeable triple-grating turrets and also includes Princeton Instruments’ exclusive AccuDrive — an advanced technology that yields significant improvements in wavelength accuracy and repeatability over previous scan systems and increases grating-to-grating wavelength precision to sub-pixel repeatability.

SpectraPro HRS-750 applications include Raman spectroscopy, photoluminescence, fluorescence, LIBS, plasma diagnostics, transmission, absorption, and microspectroscopy, among others. All SpectraPro HRS-750 spectrographs are supported by Princeton Instruments’ powerful 64-bit LightField® imaging and spectroscopy software. LightField provides complete control of the SpectraPro HRS-750 as well as comprehensive data analysis capabilities. Princeton Instruments also offers a wide selection of scientific-grade cameras and accessories (e.g., diffraction gratings, filter wheels, fiberoptics) optimized for use with the SpectraPro HRS-750 to allow researchers to customize complete spectroscopy solutions for their specific applications
