HR SERIES High resolution

/ Spectrometers

The High Resolution spectrometers

The HR series of spectrometers provides users with high spectral response and optical resolution in a single unit. HR spectrometers are used where fast reactions need to be monitored and high resolution is necessary, such as characterizing lasers, measuring gas absorbance and determining atomic emission lines.
