HR spectrometers are small-footprint, high-resolution spectrometers for applications such as wavelength characterization of lasers and LEDs, monitoring of gases and monochromatic light sources, and determination of elemental atomic emission lines. Depending on spectrometer configuration, optical resolution <0.1 nm (FWHM) is possible.

New HR4Pro preconfigured spectrometers are compact, high-resolution options distinguished by low stray light performance and great thermal stability for applications in lab, field and process environments. With a robust optical bench design and optimized components, the HR4Pro provides up to 10x improvement in thermal stability compared with similar small-bench spectrometers. Models are available for UV-Vis (200-875 nm), Vis-NIR (350-1025 nm) and extended-range (200-1100 nm) measurements.
