What is a haze meter

What is a haze meter? A haze meter, also known as a haze tester, is used to determine the optical properties of transparent and translucent parallel planar materials and plastic films. A haze meter is an optical instrument; it is not a measuring weather device. What people call haze, is also called turbidity. Transparent materials are produced in such a way that a cloudy or hazy appearance occurs inside or on the surface of the material due to light scattering. Haze can be expressed as a percentage of the ratio of the scattered light flux to the light flux through […]

What is a glossmeter

What is a glossmeter? Gloss meter is an instrument used to determine the surface gloss of ceramics, paints, inks, plastics, marble, aluminum, hardware and other materials. High precision gloss meter is divided into three types according to the angle: high gloss, medium gloss and low gloss.   Principle of glossmeter The light source G emits a beam of light through the lens L1 to reach the measured surface P, the measured surface P reflects the light to the lens L2, the lens L2 converges the beam to the photocell located at the light bar B. The photocell carries out photoelectric […]

How is chromatic aberration in photography formed

What is chromatic aberration? Chromatic Aberration, also known as color aberration, is a common optical problem, due to different wavelengths of light so that the lens can not gather all wavelengths of color to the same focal plane, or when the wavelengths of color gathered to a different focal plane position and the formation of chromatic aberration. The wavelength of visible light for the average person is between 400nm (violet) and 700nm (red). The refractive index of a material (optical glass) varies with the wavelength of the passing light wave, and is called “dispersion”. The famous “trigonometry” experiment proves the […]

What is a filter

What is a filter? A filter is an optical device used to select the desired wavelength of radiation. One commonality of filters is that no filter can make an image of a celestial object brighter, because all filters absorb certain wavelengths, thus making the object darker. Types of Filters In principle, the filters can be divided into several types. The following is an introduction to these different types of filters. Absorption filter ( Barrier filter) It is made of resin or glass material mixed with special dyes. According to the ability of absorbing light of different wavelengths, it can play a filtering […]

Measurement Application Case of Bench-top Spectrophotometer CS-828 in Metal Pr……

In daily life, our distinction of color is limited to human eyes. Human eyes can’t distinguish some objects with small color difference. In modern industrial production, the requirements for color difference are very high, and it is very important to distinguish colors effectively. For example, in the processing of metal products such as buttons and zippers, the manufacturing process has a great impact on the color difference of products. The difference and difference of processing process will cause a certain color difference of finished products. This requires to distinguish the color difference of different finished products to ensure the quality […]

Application of Spectrophotometer in platinum cobalt chroma measurement

Measurement of platinum cobalt chroma Textile, printing and dyeing, petroleum, battery and other chemical industries often produce a lot of industrial wastewater in the production process. The national standard for detecting the chroma of wastewater mainly adopts platinum cobalt colorimetry and dilution multiple method. The chroma of platinum and cobalt is expressed in Hazen unit, and the chroma of platinum and cobalt hexahydrate solution containing 1 mg of platinum (based on chloroplatinic acid) and 2 mg of cobalt chloride hexahydrate per liter of solution is 1 unit. Generally, the value range is 1-500. It is suitable for determining the color […]

With this accessory, the hand-held colorimeter can be changed into a desktop c……

Hand held colorimeter turned into tabletop spectrophotometer? You must be very curious. There are many hand-held colorimeters and desktop computers. There are great differences in body shape, structure and measurement method. It’s hard to imagine how to make the instrument transform between these two different forms. But with this accessory, liquid test fixture, as a bridge between hand-held colorimeter and desktop colorimeter, it can turn hand-held colorimeter into desktop computer, which not only retains the flexibility of hand-held colorimeter, but also increases the characteristics of stable measurement of desktop computer. Liquid test fixture — desktop construction From the picture, this […]

How to measure the gloss of special-shaped products

Gloss belongs to one aspect of human visual perception. When the buyer considers the value of the product, the gloss and color of the product have the same important position. Glossy objects look like they can emit light. They are not metal, but they have metallic luster. The glossiness of an object’s surface can be affected by many factors, such as the smoothness after polishing, the thickness and brand of the coating used, and the substrate of the object. Manufacturers will continue to introduce new designs according to the needs of buyers, such as highly reflective car panels, high-end magazine […]
