Optical System Built in Class 10,000 Ultra-Clean Environment

Paschen-Runge optical system with aberration-free performance and uniform resolution. High-luminance holographic grating with a 500 mm focal length and 2,700 grooves/mm, covering a spectral range of 130–800 nm.

Segmented exposure technology greatly enhances the identification intensity of trace elements and lowers detection limits. Single excitation with segmented exposure enables simultaneous data acquisition and readback. The integration exposure time for different CCDs can be independently controlled to boost trace element signals and reduce the instrument's detection limit. The integration time can be adjusted per wavelength band to improve instrument stability.
