Abstract

The invention discloses a spectrophotometer which comprises an LED light-emitting element array, a light-emitting element base, a measuring window, a detection system and a connecting mechanism. The LED light-emitting elements are arranged on the light-emitting element base in an array mode, and the light-emitting element base is connected with the detection system and the measuring window throughthe connecting mechanism. The LED light-emitting element array adopts a 45-degree circumferential illumination method, vertical direction receiving is used as a geometric condition, a light vertex ofthe LED light-emitting element array is located at the center of the aperture of the measurement window, and a central axis is located on the normal of the aperture of the measurement window. The LEDlight-emitting element array comprises three rows of LED light-emitting elements, the first row of LED light-emitting elements and the third row of LED light-emitting elements are white light LED light-emitting elements, and the second row of LED light-emitting elements are blue light LED light-emitting elements. The spectrophotometer provided by the invention has the effects that the spectrophotometer is more miniaturized and lighter, and the light source illumination is more stable and balanced.

Description

technical field [0001] The invention belongs to the field of optical technology, in particular to a portable spectrophotometer. Background technique [0002] In scientific research and production and life, color is an important indicator. For example, in laboratory science, accurate discrimination of color is an important basis for disease characterization; in the production of paint, automobile, textile and printing industries, accurate measurement of color is an important standard for product quality. Using a color measuring instrument to replace the human eye to distinguish colors can not only improve the measurement accuracy very effectively, but also provide effective color matching data for the computer. There are mainly two methods of color measurement instruments: color difference meter and photometer. The color difference meter directly measures the three stimulus value parameters on the surface of the object by using the principle of photoelectric integration; M...
