Our flagship, fast scanning spectrometer is for the most demanding applications including precise spectroradiometry with calibrated optical probes, spectrophotometry for measuring transmission/reflection, and as a spectrum analyzer for general optical spectroscopy. Both single and double monochromator versions are available in a compact and robust enclosure. Using up to three detectors and three gratings, a wide wavelength range from 190 to 5000 nm is possible in one instrument. The SPECTRO 320 offers an industry leading combination of dynamic range, speed, portability, and high overall accuracy.
