A digital gloss meter is an instrument used to measure surface gloss, which can measure ceramic, paint, ink, plastic, marble, aluminum, hardware and other materials. It is divided into three types according to the angle: high gloss, medium gloss and low gloss.
Measuring principle of gloss meter
The measuring head of the instrument consists of an emitter and a receiver. The emitter consists of an incandescent light source and a set of lenses, which produces a certain required incident light beam. The receiver consists of a lens and a photosensitive element, which is used to accept the cone-beam reflected back from the sample surface. The colorimeter is widely used in the color management field of plastic, printing, paint and ink, textile, printing and dyeing garments and other industries. According to the Lab, Lch principle of CIE color space, it measures and shows the color difference △E and △Lab value between the sample and the sample under test. It is suitable for internal and external color evaluation and data control.
The difference between gloss meter and colorimeter
First, the use: The main difference between the gloss meter and colorimeter lies in the use, the former is to test the gloss of the product surface, the latter is to test the difference in product color.
Second, the test angle is different: gloss meter commonly used test angle of 20 degrees, 60 degrees, 85 degrees. Chromatic aberration meter test angle of 8 / d (8 ° lighting / diffuse by light), including specular reflection of light (SCI)
Third, the main technical characteristics:
Glossmeter: The measuring head of the instrument consists of an emitter and a receiver, the emitter consists of an incandescent light source and a set of lenses, which produces a certainly required incident beam. The acceptor consists of a lens and a photosensitive element, which is used to accept the cone-beam reflected back from the sample surface.
Colorimeter: Simulates D65 illuminator illumination. Use CIE 1964 supplementary colorimetric system and CIE 1976 (L*a*b*) color space color difference formula.
