In fields such as color management, quality control, and product development, color accuracy is crucial for ensuring product quality and meeting customer expectations. Spectrophotometers, as highly accurate and efficient color measurement tools, play an indispensable role in these areas. Working Principle of Spectrophotometers Spectrophotometers operate based on spectral and photoelectric conversi...
A spectrophotometer is an instrument used to measure the reflected spectral power and light characteristics of objects to determine their standard color values. However, measurement results can vary due to differences in color difference calculation methods and light source selection. Therefore, it is crucial to carefully select appropriate color difference formulas and light sources when using a ...
What is Spectrophotometer? Spectrophotometer is a color measuring instrument with excellent performance, wide use, and easy operation. This instrument is suitable for color detection and color difference control of complex products in industry, such as measuring the reflected and transmitted colors of objects, while also measuring the whiteness, chromaticity, and the most basic color difference be...
What is a spectrophotometer? The spectrophotometer uses the grating spectrophotometer principle for color measurement. A grating is an optical element that is engraved with a set of parallel periodic lines or grooves (often inclined) on a plane. When a beam of compound light is incident on the grating plane, its periodic structure will undergo diffraction, and the transmitted or reflected diffrac...
The spectrophotometer has high accuracy and uses a pre positioning board setting, eliminating the need for standard blackboards and whiteboards in the calibration process of traditional colorimeters and colorimeters. The built-in software has powerful functions, including all necessary color equations, standard light sources suitable for different tasks, and a large number of specific industry an...
Almost all colors can be mixed with three primary colors in a specific proportion. None of the three monochromatic lights can be produced by mixing the other two. In 1931, CIE (International Committee for Standardization of Lighting) established a series of CIE standard chromaticity spaces representing the visible spectrum and defined the CIE-RGB primary color system. It is specified that the wave...
Fluorescent materials are made of metal (zinc, chromium) sulfide or rare earth oxide and trace active agent by calcination. The color is generally colorless or light white. It is the visible light (400-800nm) of various colors under the irradiation of ultraviolet light (200-400nm), depending on the type and content of metal and activator in the pigment. Fluorescent materials absorb light of a cert...
The spectrophotometer is a color measuring instrument with superior performance, wide use, and easy operation. This instrument is suitable for color detection and color difference control of complex industrial products, such as measuring the reflection and transmission colors of objects, as well as measuring the whiteness, chromaticity, and the most basic color difference between two objects. Cur...
During the day we can see colorful colors, but at night all objects turn black. Relationship between object color presentation and spectrophotometer. 1. Different objects will have different colors, so the color must be related to the attributes of the object itself. 2. In different light environments, the same object will present different colors, such as the apple below. The color is different i...
The optical system is the core part of the spectrophotometer. Based on the basic principles of the spectrometer and optical design theory, with the specific design goal of portability, low cost, and meeting the design requirements of the spectral range and resolution, four feasible design schemes, namely the Littrow system, the Albert Fastian system, the Cherney Turner system, and the crossed Cher...
The instrument for detecting the color of an object can be called a colorimeter. However, there are many kinds of colorimeters, including colorimeter and spectrophotometer. There are many products of color difference meter and spectrophotometer on the market, which makes many customers often feel headache about which product to choose when selecting this product. Today, let’s talk about the ...
Spectrophotometer is a high-performance spectrometer specially designed to measure liquid transmittance, absorbance, concentration, chroma and other parameters. In addition to measuring the liquid transmittance, the instrument also includes APHA/PtCo (APHA/PtCo) and Gardner (Gardner Index) chromaticity scales for resin, solvent, acid, perfume, varnish and other products; Saybolt color scale for me...
