Spectrophotometer

Abundant uses:

Color Measurement and Management:

The spectrophotometer can be used to measure the surface color of the object, as well as the color difference of the object's standard sample and the sample color, so as to achieve accurate color management.

Spectral response analysis:

The instrument can measure the absorption rate, brightness （known by L） and other spectral response parameters of the sample, which is helpful to understand the optical characteristics of the sample.

Heterochromatic phenomenon detection:

The spectrophotometer can be used to detect the phenomenon of heterochromatism of samples, that is, the phenomenon that the color behaves the same under different light sources but there are differences in the spectral distribution.

Quality control:

In the industrial field, the spectrophotometer is widely used in printing, coatings, plastics, textiles, automotive and other industries to measure the color of pigments, paints, plastics, textiles, automotive coatings and other materials to ensure product quality and consistency.

Formula adjustment:

By measuring the color difference between different batches of dyes, the spectrophotometer helps to adjust the formula and ensure the consistency of the dyeing effect.

Color fastness evaluation:

A spectrophotometer can be used to assess the color fastness of a sample, that is, the persistence and stability of a sample's color under certain conditions.

Research and Teaching:

In the field of scientific research, spectrochromometer can be used to study color science and explore the nature, production and perception mechanism of color. At the same time, it can also be used as a teaching tool to help students gain an in-depth understanding of the source and method of color measurement.

Applicable standards:

The applicable standards of the spectrophotometer mainly include the following aspects:

CIE color measurement standard:

Spectrometers need to meet a number of color measurement standards set by the International Commission on Illumination （CIE）。 For example, the four standard lighting and observation conditions for color measurement recommended by C （0/d, d/0, 0/45 and 45/0）， as well as the standard lighting body and standard light source specified by CE.

Measurement accuracy and stability:

The spectrophotometer needs to have high precision and stability to ensure the accuracy and reliability of the measurement results. This is usually achieved through regular calibration and maintenance.

Data transmission and processing:

In the process of color measurement, it is necessary to ensure the accuracy of measurement results and the reliability of data. Therefore, the appropriate measurement software should be selected and the data transmission and processing should be carried out in accordance with the standard data transmission format.

Industry Standards and Specifications:

Depending on the characteristics and needs of different industries, spectrophotometers may need to meet specific industry standards and specifications. For example, in the printing industry, it may be necessary to meet laboratory accreditation standards such as ISO/EC 17025; In the automotive industry, it may be necessary to meet specific automotive paint color measurement standards, etc.
