Princeton Instruments has announced three new configurations of its LS 785 NIR lens spectrograph for Raman and fluorescence applications. The systems combine the company’s PIXIS deep-depletion CCD cameras with its Acton Series LS 785 spectrographs, to provide an easy-to-use spectrometer. The spectrographs have gold-coated gratings for increased efficiency. Tunable center wavelength adjustment allows 785-, 805- or 830-nm excitation. The proprietary lens design offers 94 percent transmission through the combined lens sets and 65 percent total system throughput.
