Versatile new SpectraPro® HRS-300 high-resolution imaging spectrograph includes exclusive spectral deconvolution technology

April 17, 2017

Princeton Instruments is pleased to introduce its SpectraPro HRS-300, which is engineered to deliver both the outstanding spectral resolution and the astigmatism correction needed for advanced microspectroscopy and multichannel fiber applications. This 300 mm imaging spectrograph’s optical performance is further optimized via ResXtreme™, an exclusive new spectral deconvolution technology from Princeton Instruments that is provided with every SpectraPro HRS. ResXtreme can improve spectral resolution, peak intensities, and consistency across the 2D focal
plane by as much as 60% with the push of a button.

The SpectraPro HRS affords researchers truly unrivaled experimental versatility. Dual exit ports, each with a full 30 mm focal plane, permit mounting and operation of two array detectors (which could include any of Princeton Instruments’ CCD, EMCCD, ICCD, sCMOS, or InGaAs detectors) or enable the instrument to operate as both a monochromator and a spectrograph. Every SpectraPro HRS can also utilize as many as three interchangeable triple-grating turrets and includes Princeton Instruments’ exclusive AccuDrive™, a new grating drive system that yields significant improvements in wavelength accuracy and repeatability over previous scan systems and increases grating-to-grating wavelength precision to sub-pixel repeatability.

 “Furthermore, to ensure highly accurate and reproducible spectroscopic data that can be published or shared across multiple user facilities, we have designed the new SpectraPro HRS-300 to be utilized with our patented IntelliCal® wavelength and intensity calibration system,” notes Michael Case, spectroscopy unit manager at Princeton Instruments. “IntelliCal’s push-button wavelength calibration routine 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 your spectral data.”

SpectraPro HRS applications include Raman spectroscopy, photoluminescence, fluorescence, LIBS, plasma diagnostics, transmission, absorption, and microspectroscopy, among others. SpectraPro HRS spectrographs are supported by Princeton Instruments’ powerful 64-bit LightField® imaging and spectroscopy software. LightField.

provides complete control of the SpectraPro HRS 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 to allow researchers to customize complete spectroscopy solutions for their specific applications.
