HR4Pro Spectrometer 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.
