A portable color measuring instrument

Abstract

A portable color measuring instrument of the invention belongs to color measuring equipment in the field of optical measurement. The appearance of the portable color measuring instrument of the present invention is a cuboid, and a handle, a measurement button and a touch screen display are designed on the top, and a measurement window and a measurement bottom cover are designed on the bottom. The portable color measuring instrument is composed of light source, integrating sphere, condenser, monochromator, array CCD sensor, analog-to-digital converter, microprocessor, memory, power supply and other components. After the measuring light is collected and homogenized by the integrating sphere, it is spectroscopically and measured by the high-resolution monochromator and array CCD sensor, and the color parameters are calculated by the microprocessor with reference to ISO and other standards. The excellent design ensures that the portable color measuring instrument has the advantages of high measurement accuracy, good repeatability, high measurement efficiency, convenient portability, and simple operation. It can be widely used in production lines of cloth, paper, dyes, paints, beverages, plastics, etc. Color measurement of raw materials and products.

Description

technical field [0001] The invention belongs to color measuring equipment in the field of optical measuring instruments, and in particular relates to a portable color measuring instrument. Background technique [0002] The objects that people can see all have a certain color, so color is an important sensory experience for human beings. In daily life, people can qualitatively describe the colors of the objects they observe through simple red, orange, yellow, green, blue, indigo, and purple. However, in some specific production fields, specific parameters are required to quantitatively describe the color of the measured material. [0003] Ordinary spectrophotometers are very powerful in optical measurement, and can measure parameters such as transmittance, reflectance, absorptivity, and solution concentration of materials. Of course, the color of different materials can also be accurately measured, and the color of the measured material can be quantitatively described by sp...

Problems solved by technology

However, ordinary spectrophotometers are cumbersome to use on-site in the production line, mainly in the following aspects: First, ordinary spectrophotometers are relatively large in size, not easy to carry, and have high requirements for the use environment, and special space needs to be planned Second, the operation method of ordinary spectrophotometers is relatively complicated, and professionally trained personnel are required to operate on the machine; third, ordinary spectrophotometers generally adopt the measurement method of wavelength scanning, and the measurement of a single sample Long time, low measurement efficiency
