Color Measuring Products
Full Spectral Color, Hand-held Spectral, Color, Color Difference, Spectral Colorimeter Measuring Product
As the concept of accurate reproduction of the image promotion gradually, which color measuring equipment is appropriate?
Color belongs to the measurement of the visible light from the wavelength range of 400nm ~ 700nm, and then use the spectrum to calculate the color measurement, color measurement instrument is to measure the object of the light source or color using this model to calculate the chromaticity coordinates.
There are two main color measuring instruments - colorimeter and spectrometer.
The general colorimeter approach is to add three kinds of filters in front of the monochromatic sensor, and then calculate the chromaticity coordinates, but in fact the exact same optical filter can not be achieved, so the colorimeter for different spectral measurement object accurate Degree is not ideal. But the advantages of colorimeter is the measurement speed, cheap.
Rainbow-Light in the spectrometer application, the introduction of full-spectrum color measurement products, is the use of complete visible spectrum, because the amount of spectral data integrity, so it is not suitable for different shades or light source of the problem, Have the correct results. Because it is the measurement of the whole spectrum, it can measure the reflection of the draft, this aspect of the colorimeter is difficult to do.
So what kind of color measuring instrument is appropriate? Colorimeter is generally used as a practice equipment, the accuracy is not reliable. If you pay attention to the accuracy of color measurement, palm light Rainbow-Light full spectrum color measurement products with applicability.
Palm light Rainbow-Light full spectrum color measurement products, can immediately display L * a * b *, E *, CIE X, CIE Y, CIE 1976 ... and so on the measured value. It can be used in measuring food, medicine, plastic, chemical, automobile, paper, paper, printing, dyeing, electroplating, painting, etc. Cosmetics, tapes, cultural relics and calligraphy, etc. quality control or finished product acceptance.
