Choosing The Right Portable Color Spectrophotometer For Your Needs

With the development of science and technology, more and more people begin to pay attention to the detection of color quality, especially in industries such as coatings, fabrics, packaging, building materials, plastics, and electronic products. In order to meet the various needs of customers, portable spectrophotometer is a common color detection instrument that has been widely used in more industries.

Portable color spectrophotometer is a color measuring instrument with superior performance, wide range of uses and easy operation. This instrument is suitable for color detection and color difference control of complex industrial products, such as measuring the reflected color and transmitted color of objects, and can measure objects at the same time The whiteness, chromaticity and the most basic color difference between two objects. The spectrophotometer uses a 45°/0° geometric observation angle suitable for human eyes to display the reflectance and transmittance of objects in the visible light band 300nm-700nm quality inspection list, and connects to the computer through the interface to expand more Function.

Now in industrial production, portable color spectrophotometers are mainly used in textiles, printing and dyeing, coatings, metal paints, glass coatings, paint films, building materials, printing and other industries with stricter and difficult to control color requirements. The quantitative comparison and analysis of the product’s color information can be seen at a glance. At the same time, it can be used together with a PC to restore the color information clearly, providing the best guarantee for color transmission and reproduction.
(λ) are multiplied by the CIE spectrum cubic excitation values separately, and these products are integrated separately over the entire visible spectral range. According to the standard chromaticity system stipulated by the International Commission on Illumination CIE, the calculation method of the third excitation value of the color is the color stimulus function

This formula is the main basis for the portable color spectrophotometer to realize color detection. It can perfectly convert the measured color lightness, brightness, and chromaticity information into different color information, and finally realize the measurement of whiteness, chromaticity, and color difference.
(λ) can be respectively represented as equal to three kinds from different measured objects. of which
(λ)=S(λ)——(self-luminous body) relative spectral power distribution 
(λ)=β(λ)S(λ)——the product of the reflectivity factor (reflective object) and the relative spectral power distribution of the standard illuminator. 
(λ)S(λ)——the product of the transmittance factor (transmitting object) and the relative spectral power distribution of the standard illuminant (λ)=

At the beginning of the research and development of  portable color spectrophotometer, the R&D personnel will consider the configuration suitable for different industries, products and measurement environments, including the choice of light source (A, C, D65, D50, etc.), and a variety of color difference formulas to choose from. In addition, according to The qualified requirements of the product set the tolerance range, which can quickly detect the color difference of the product, and is suitable for color control in industrial mass production.

The portable color spectrophotometer is an instrument for spectrophotometric measurement of object color based on the theory of optical colorimetry. It is composed of a light source, an integrating sphere, a spectrometer, a detector, and a data processing system. The main purpose of the research and development and mass production of this instrument is to facilitate users to analyze color data intuitively and reliably, transmit color information, and reproduce color images. Now both domestic and foreign color management instrument companies are working hard on spectrophotometers, striving to develop and produce more suitable and practical instruments.

Features of Spectrophotometer：
We know that light is observed by the human eye in the form of electromagnetic waves. Light of different wavelengths presents us with different colors on the color spectrum. In the spectrum, red light has the longest wavelength and violet light the shortest. The others are arranged in the order of red, orange, yellow, green, indigo, and purple. The portable color spectrophotometer analyzes the light using the rules of the spectrum.

Generally, there is a compound sensor in the portable spectrophotometer to measure the spectral reflectance of the wavelength of the object, and the third excitation value is calculated by using the color difference calculation method of the internal equipment of the spectrophotometer to calculate the spectral reflectance data with a microprocessor. With the three excitation values, we can calculate the color information we need according to the calculation formulas of different chromaticity spaces provided by CIE.

For a portable spectrophotometer, it not only has all the functions and features of a general colorimeter, but also has higher sensitivity, because the script spectral sensor measures light at various wavelength intervals, so the colorimeter generally operates at △E*ab Between 0.01 and 0.02, it can be said that the error is very small. The measurement speed is much faster than that of ordinary colorimeters. It can measure both, and the measurement time is about 0.3s. This application in mass industrial production color detection can greatly improve the speed of color detection and improve production efficiency.

The portable spectrophotometer can perfectly realize the detection, analysis, transmission, communication and reproduction of colors, which are the most common functional requirements for using this instrument in industry. So a spectrophotometer can help you solve all color problems, which is really a good way to serve multiple purposes.

How to choose the right spectrophotometer?
1. Determine the purpose of use
Before purchasing a portable spectrophotometer, first determine the purpose of use. Beyond basic color measurements, there are some metrics to consider. For example, someone needs to test the spectral restoration index, someone needs to measure gray scale, color difference and so on. For different industries and usage scenarios, different functions and performances need to be selected.

2. Measuring range and accuracy
Measurement range and accuracy are also key factors in selecting a portable spectrophotometer. If you need to measure some smaller sample areas, then you need to choose a model with a higher resolution. In addition, some knowledge of measurement accuracy is required as needed. Typically, spectrophotometers have a minimum measurement of 0.01, and there are higher models that can achieve a measurement accuracy of 0.001.

3. System stability and repeatability
System stability and repeatability are key specifications for a portable spectrophotometer. They measure the consistency and accuracy of portable spectrophotometer measurements. When choosing, you need to pay attention to checking the stability and repeatability of the equipment. If these two indicators are insufficient, you should look for other spectrophotometer models.

4. Equipment upgrade and maintenance
Due to the rapid development of technology, portable spectrophotometers are constantly being upgraded. Therefore, before choosing a model, you need to check whether the manufacturer provides equipment upgrades and maintenance service support. This can help extend the life of your device and improve its performance and functionality.

5. Reference Specifications
Finally, you also need to consider the various specifications and standards that you need to meet in the operation process. Different industries and usage scenarios have different standards. Therefore, when choosing a spectrophotometer, it is necessary to choose a model that meets various criteria.
