Features：

High resolution, wide measurement range and   ultra-low stray light

High-performance dual-grating monochromator is   used to achieve high resolution (resolution up to 0.1nm) and ultra-low stray   light (less than 0.00005% of stray light at 340nm). The measurement   wavelength range is 185nm-3300nm, which can be measured in a wide range of   ultraviolet, visible and near-infrared, to meet the measurement requirements   of different fields.
