LSH illuminator

The HORIBA LSH series illuminator is a high-stability, broadband light source based on a xenon arc lamp, providing continuous illumination from the UV through the visible to the near-infrared spectral range. Xenon arc lamps produce a smooth, broadband emission spectrum that closely resembles sunlight, making the LSH illuminator well suited for applications that require uniform, high-intensity illumination across a wide wavelength range: photoluminescence (PL) excitation, UV-VIS-NIR absorption and transmission spectroscopy, solar simulator applications, optical fiber coupling, and general optical bench illumination. The LSH series features careful lamp housing design to ensure stable arc positioning, minimal flicker, and reproducible output, which is critical for quantitative spectroscopic measurements and time-resolved experiments. A calibrated reference photodiode can be used for output monitoring and intensity normalization. The optical design incorporates efficient collection optics and output beam conditioning (collimated or focused) to couple efficiently into monochromators, fibers, or sample illumination setups. The lamp power levels range from compact desktop models to high-power versions for demanding applications. Compatible with HORIBA monochromators, spectrofluorometers, and photoluminescence mapping systems, the LSH illuminator is designed to integrate into complete optical spectroscopy workstations. NewRoad provides the HORIBA LSH illuminator in Israel for universities, photovoltaics research laboratories, materials characterization groups, and spectroscopy instrument builders requiring reliable broadband UV-VIS-NIR illumination.
