The YS4560 high-precision spectrophotometer adopts a 45/0 (45-degree ring illumination, 0-degree reception) geometrical optical structure that conforms to CIE No.15, and adopts a concave grating spectroscopic method, which can accurately measure sample reflectance and various chromaticity data. The instrument is equipped with Φ8 and Φ4mm dual measuring calibers, which are used for accurate color measurement and quality control in traffic road signs, plastic electronics, paint inks, textile and garment printing and dyeing, printing, ceramics and other industries. The instrument has a separate UV light source, which can be used for fluorescent sample measurement. The instrument has built-in standard colors of GB 2893 and GB/T 18833, and the tolerance of polygonal rectangles can be customized manually. One-key can realize the measurement of luminance factor and chromaticity coordinates of traffic road signs, marking lines, and reflective films.
Under the 45/0 geometrical optical lighting conditions recommended by CIE, the instrument can accurately measure the reflectance data of samples/fluorescence samples, and can accurately measure and express various color difference formulas and color indices in various color spaces. With the aid of this instrument, accurate color transfer can be easily achieved, and it can also be used as a testing device for a precise color matching system. The instrument is also widely used in the quality control of color difference of various products. The instrument is equipped with high-end color management software, which can be connected to a computer to achieve more functional expansion.

The grating spectrometer can easily achieve accurate color transfer, and can also be used as a detection device for a precise color matching system; it is used for accurate color measurement and quality control in industries such as traffic road signs, plastic electronics, paint inks, textile and garment printing and dyeing, printing, and ceramics; instruments There is a separate UV light source, which can be used for fluorescent sample measurement.
