iHR320 Imaging Spectrometer


The iHR320 provides a platform for spectroscopic measurements for years to come. The design of the spectrometer itself and its accompanying accessories and software enables users to customize the iHR for any experiment. This customization starts with the choice of entrance and exit ports, the library of HORIBA Scientific gratings, and the full line of spectroscopic accessories for various measurements. SynerJY, our general purpose spectroscopy software based on Origin software, provides a platform for most measurements. Additional software possibilities are available, including our Software Development Kit and LabVIEW VIs.
