The Rangqi G-11 dual-beam UV-Vis Spectrophotometer can cover the full spectrum range of UV-VIS-NIR and realize continuous scanning of the UV-Vis-NIR band, which has a wide range of applications, and can measure the characteristic absorption of solid/liquid samples in the UV-Vis and near-infrared range, can study the absorption/transmission or reflection spectra of glass-coated samples, and can study the absorption spectrum of powder samples in the entire UV-Vis near-infrared region. It can also measure the content of nucleic acids/proteins or detect the activity of enzymes, etc., and is suitable for semiconductors, optical components, building materials, new materials and other industries, and is a powerful spectral analysis instrument.

1. The classic Czerny-Turner optical structure is adopted, which has a simplified structure, high precision and good spectral resolution;
2. The design of double grating and double receiver ensures that the working band of the instrument can cover the full range of ultraviolet visible and near-infrared region (UV-VIS-NIR);
3. The receiving devices are all imported devices, which ensures the high performance and stability of the instrument;
4. The grating adopts 55×55mm large-area grating, which effectively improves the efficiency of light collection;
5. The control of the instrument (such as grating conversion, filter conversion, receiver conversion, wavelength scanning, etc.) is all controlled by the computer, the interface is USB2.0, and the connection of the instrument is simple, which greatly improves the communication rate;
6. There are 7 levels of slit width to choose from, which are (0.1nm, 0.2nm, 0.5nm, 1.0nm, 2.0nm, 3.0nm, 5.0nm). Users can choose arbitrarily according to their actual needs.
7. Full Chinese operation software, simple and easy to understand function selection.
