Color Spectrophotometer Colorimeter Instrument for Color Analysis

The accuracy of colorimetric values in modern manufacturing units, research, and quality control, especially at global scale, is very fine as even the slightest deviation of color dye in the paint can cause loss of control in lot acceptance, protection of brands, and unsatisfactory results for clients. Industries are dependent on these tools, as a portion of the colorimetric devices, black box, is in color viewing filters i.e. the black box is a color filter.

Color spectrophotometers measure color without the prejudice of a human. Corporations get control of the uniformity of color without the impressionistic judgement.

The demand in quality control and the market is met through diverse manufacturing industries like cement, plastics, paints, coatings, food, pharma, textiles, and even more in automotive and paint factories.

Color spectrophotometers are color analyzers

Color spectrophotometers are color analyzers. They are optical, expert devices that detect and quantify color relating to the interaction of light on a sphere. This interaction can depend on transmitted or reflected light in the visible range, which is from 400 to 700 nm.

Within the field of measurement science, the spectrophotometer is one of the more curious instruments. Specifically, the device uses luminous energy while trying to characterize the specific components that constitute the energy.

● CIE L*a*b*

● XYZ tristimulus values

● ΔE color difference

● Spectral reflectance or transmittance curves

Manufacturers and laboratories can detect and maintain tolerances on colors due to these values. Scientific data are produced from the spectrophotometric color analyses, because the analysis is objective and sight is not an issue.

Color Variation is Regulatory Compliance. Brand Identity is the primary product. Color Variation is the primary product in many. Whether color matching a corporate identity, keeping a color constant in production, or meeting International Specifications the spectrophotometer offers the assurance required for color critical decisions.

Basic principles of color spectrophotometry

One of the methods used to create accurate measurements in spectrophotometry is to have standard and controlled illumination of the sample as well as controlled measuring of the transmission and reflection of the sample, illumination the sample at each wavelength.

By measuring and representing the entire spectrum of light reflected or transmitted, one can obtain the entire profile of the color of the sample precisely. While colorimeters are less accurate and more limited by using human color perception by blocking certain ranges of the spectrum, spectrophotometers are more flexible and accurate as they measure with all and every wavelength of light in the visible spectrum.

More recently built color spectrophotometers have the following features.  

● Input stability light sources to color spectrophotometers are designed to provide stable illumination, reducing optical noise.

● Measurement uncertainty is reduced by the use of high quality optical systems to construct the spectrophotometers.

● The use of high quality signal detectors and high performance computer systems is implemented, designed to process and deliver coordinated data reports.

All of the added components are the result of designed illumination and observer control as regulated by CIE, ISO and ASTM organizations. This original configuration allows for flexible spectrophotometers designed for dependable use in research, including but not limited to, product design, quality control, and compliance with regulations.

Procedures Performed by a Color Spectrophotometer

To analyze a sample using a color spectrophotometer, a controlled light source is aimed at the sample's test surface. Once illuminated, the sample will either reflect, transmit, or absorb the light, depending on the composition of the sample material.  

The light that is reflected or transmitted will be captured by the optical system. This light is then separated by a monochromator or diffraction grating into its individual wavelengths, and each of these wavelengths are recorded serially to ensure the data is accurate and of high quality.  

The following is a configuration of how the process is usually done:  

● Illuminating the sample with a standard light source.  

● Logging the light that is reflected/ transmitted.  

● Dispersing the light into its component wavelengths.  

● Eliminating the light intensity.  

● Digitizing the light.  

● Calculating the color values based on standard values (L*a*b*, XYZ, ΔE).

● Performing a result analysis depending on the reference values.  

It is the only software capable of calculating such differences. Such software can create values of color, difference, tolerances, and pass/fail statuses. Not only is this form of measurement a science, but it is one’s measurement science. It is as precision, trustworthiness, and repeatability. Such traits and characteristics is the speck of measurement industry dominator.  

Benchtop Color Spectrophotometer  

Benchtop color spectrophotometer are fabricated and engineered with a specific purpose for the laboratory and controlled space. Such spaces require for the measurement to be accurate and stable over a long period of time.

Benchtop spectrophotometers are differentiated with having fixed measurement systems, high resolution optical systems, and large sturdy calibration systems. With environmental variables being controlled, these tools are giving the best precision within the industry.

What Makes Benchtop Spectrophotometers the Best Option for Your Color Analysis?

When it comes to the field of contemporary colorimetric theory spectrophotometric analysis, use of benchtop spectrophotometers is very instrumental to determining color accuracy due to calibrated measurement control, measurement reproducibility, and measurement constancy over extended timeframes. Spectrophotometers in long-term varied environment scenarios will deliver results that will remain unaffected by the measurement control exercised over the spectrophotometers ambient/control environment.

Such processes enable consistent color quality throughout production, significantly reducing waste, rework, and downtime.

Inline Color Spectrophotometer

Inline color spectrophotometers are designed into production lines to provide seamless automated color monitoring. This integration is essential for high-throughput manufacturing systems, where manual sampling is unfeasible.

Industries that make use of inline spectrophotometers include:  

● Plastic injection molding and extrusion  

● Surface treatment and coatings  

● Nonwovens and textiles  

● Paper, film, and packaging

Grating Spectrophotometer  

A grating color spectrophotometer uses diffraction gratings to break light into its constituent wavelengths. This technology provides greater resolution of the light spectrum than systems that use light filtering.  

Grating-based systems are used in pigment science, materials science, and for other increasingly complex applications that require the use of a color matching spectrophotometer.  

These systems are most preferable in opaque and complex samples that have small color differences which may affect the sample's visibility, or influence the sample's usability or effectiveness, because of their ability to detect micro-spatial spectral differences.  

Buy a Color Spectrophotometer  

When buying a color spectrophotometer, it is most important to consider the application requirements, measurement precision, type of sample to be measured, sample surroundings, and the budget available.
