QM-5 NIR Steady State Spectrofluorometer

Near-infrared (NIR) spectroscopy has emerged as a valuable analytical technique, especially in the fields of material research, chemistry and photomedicine. Powerful NIR capabilities are available through PTI as either a stand-alone research grade fluorometer or as an upgrade to PTI’s UV-VIS steady state spectrofluorometers.

NIR-InGaAs Based SteadyState Systems
Comprised of a high intensity xenon light source, scanning monochromators, a high sensitivity TE-cooled InGaAs detector, electronics, lock-in amplifier and chopper for noise suppression. The system provides unmatched NIR capability from 500 to 1700 nm or an extended version out to 2.2 microns.
