1. Adopt the world's first hybrid C-T double single-device optical system, equipped with special coated high-reflection optical devices, which not only ensures the high resolution of the optical system, but also effectively improves the luminous flux of the system, and realizes the ultra-low stray light of the instrument ≤ 0. 00004% T (220nm); 
 

2. The high-performance deuterium lamp is used as the ultraviolet light source of the instrument, and the ultraviolet enhanced high-sensitivity photomultiplier tube is used as the detector, which can realize a wide wavelength range of 185nm ~ 900nm, and can realize deep ultraviolet measurement below 185nm when purging with nitrogen;

3. The discrete three-slit combined continuous variable slit design can automatically scan the spectral bandwidth in the range of 0.1 nm ~ 5.0 nm, and identify the spectral bandwidth of sample molecules during resonance absorption, so as to determine the experimental conditions;

4. Modular design, providing an open optical platform and electrical interface, which is convenient for researchers to carry out secondary development according to their work needs;

5. In addition to providing two working light sources of high-performance deuterium lamp and long-life tungsten lamp, a wavelength calibration light source is also built in, which is convenient for users to calibrate wavelengths when needed and ensure the accuracy and reliability of measurement data;

6. The fully enclosed structure design is adopted, which realizes efficient isolation from the external environment, prevents the performance degradation of optical devices caused by dust and corrosive gas invasion, and fully guarantees the service life of the instrument.
