A colorimeter is used to measure absorbance at selected wavelengths with the help of filters, which is suitable for rapid comparison of colors. A more advanced spectrophotometer has a monochromator. It can measure a larger range of the spectrum of light and is more accurate. You can also get detailed color data at visible and non-visible wavelengths.

A Spectrophotometer color measuring device objectively determines the color of a surface. It is used wherever accurate color matching, reproducibility or deviation control is needed – for example in quality assurance, product development or incoming goods inspection.

Spectrophotometer color measuring devices primarily perform three key tasks:

Capture color information: They detect light reflected, transmitted, or emitted by a sample using optical sensors.
Quantify color data: They convert the captured optical signals into standardized numerical values, such as RGB, CMYK, or CIELAB coordinates.
Compare color consistency: They compare the measured color data of a sample against a target or standard to assess color accuracy and uniformity.

A colorimeter measures the amount of light and the wavelength that is absorbed by a solution. It is a sign that colored compounds are present and the level of their concentration. It is applied in the laboratory and industry to check the concentrations of chemicals, the color of products, and purity.

The various colors can be measured by the way a surface reflects, absorbs, or transmits light at different wavelengths. These responses may be measured using instruments such as colorimeters or spectrophotometers to give numeric values in a standardized color space such as L *a*b*.

D/8°and 45°/0°are two kinds of illumination geometry with different optical geometry design. D/8°illumination geometry is more widely used for the color comparison and measurement of high-gloss materials; 45°/0°illumination geometry is mainly used in printing and packaging industries. 

Pick a haze meter that correlates with your materials, precision needs, and applicable testing protocols. For lab-level precision, a bench-top version is advisable; for a rapid field check, a portable haze meter is appropriate. International standards must be met at all times.

SCI&SCE are two method in the color measurement. SCI means Specular Component Include,SCE means Specular Component Exclude.

Under the method of SCE, only test diffuse refection and exclude specular reflection. In that way, the test result is similar to object color was observed by human eyes.

Under the method SCI, both the diffuse refection and specular reflection will be included. In that way, the value about the color is more objective. It will not effect by the environment condition.

When we choose the instrument, those elements should be taking into consideration.

A light booth for color matching usually contains D65 (daylight), TL84 (store), A (incandescent) and UV light. LED may also be used in modern time for additional color matching. 

You can choose a colorimters depending on the substrate you are measuring the color of, whether it is opaque, translucent or transparent. In short, you can consider the following factors for choosing the right 3NH colorimeter for your needs: Sample Opacity, Physical Form, Optical Properties needed, Measurement Methods required, Scales and Indices needed, Instrument Standards Conformance (ASTM/ISO/Other), Instrument Geometry, Instrument Performance, Location (laboratory, portability, in-process) and Sample Handling requirements.

By systematically addressing these factors, you can select a colorimeter that optimizes accuracy, efficiency, and value for your specific application.Learn more from our ultimate guide on colorimeter selection. If unsure, consult the 3NH manufacturer for personalized recommendations based on your sample and workflow.
