Spectrocolorimeter Geometry

The d/8 (diffuse/8 degree observation) geometry is a common structure for spectrocolorimeter, which means that the light source is evenly illuminated on the sample surface through a diffuser (such as an integrating sphere), and the observation angle is fixed at 8 degrees. This geometry can simulate a variety of real-world lighting conditions, making the measurement more accurate and able to measure materials with different surface characteristics.

SCI/SCE mode:

SCI (Specular Component Included): Contains specular reflection components, which are used to evaluate the overall appearance and glossiness of the material.

SCE (Specular Component Excluded): Excludes specular components, focuses on surface color, and is not affected by gloss.

Through SCI/SCE technology, the Spectrocolorimeter can flexibly choose whether to include specular reflection light during measurement, which is suitable for more accurate analysis of surface gloss and color.

Spectrocolorimeter Features and Benefits:

High accuracy and repeatability : The biggest advantage of the Spectrocolorimeter is that it provides highly accurate color data through full spectrum analysis. It can measure a variety of optical properties including reflectance, transmittance, and surface gloss, and is particularly suitable for color measurement under strict lighting conditions.
Full spectrum measurement : The instrument is able to analyze the visible light spectrum from 400nm to 700nm, ensuring accurate measurement results even in complex lighting environments. Especially when dealing with fluorescent materials or high-gloss surfaces, the Spectrocolorimeter can easily cope with it, avoiding spectrum loss or inaccurate measurements.
Flexible geometry : Spectrocolorimeter usually adopts d/8 (diffuse/8 degree observation) or SCI/SCE mode, which can flexibly choose whether to include specular reflection light. This makes it more flexible and accurate when measuring glossy surfaces.
Advanced Color Management : The Spectrocolorimeter is equipped with SQCX software, which enables comprehensive color analysis and data management. It can record data in multiple color spaces, generate detailed test reports, and allow customization of color management processes to improve the efficiency of quality control.

FAQs About Spectrocolorimeter

The LAB color space defines colors in a three-dimensional model: Lightness (L), red–green axis (a), and blue–yellow axis (b). It's a globally recognized standard supported by most modern color measuring devices. CIELAB is a standardized, device-independent system designed to map all visible colors that the human eye can perceive.

The LAB color space uses three values to define any color, each representing a specific dimension:

L (Lightness): Ranges from 0 to 100. It measures the brightness of the color, where 0 is pure black and 100 is pure white.
A (Red-Green Axis): Ranges from approximately -128 to +127. Positive values represent red tones, while negative values represent green tones.
B (Yellow-Blue Axis): Ranges from approximately -128 to +127. Positive values represent yellow tones, while negative values represent blue tones.

To quantify color change, take the original L*a*b* values of a sample, and reread after exposure or processing. Compute the difference as 1/2(Emut1 Emut2). The larger the value of ΔE, the more obvious the change of color is, which can be used in quality or stability testing.

The most important equation is A = 2εcl, where A is the absorbance, 2 is a constant, ε is the molar absorptivity (L/mol cm), c is the concentration (molL-11), and l is the path length (cm). This can be used to relate the absorbance to the concentration, allowing quantification through colorimetric assays.

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 colorimeter is sufficient when measuring similar materials or batches with stable conditions. Suitable for fast, low-cost color checks where high precision is not required. Quick quality control in plastics, paint batch consistency, food color grading (e.g., fruit ripeness), and basic printing checks.

A spectrophotometer is recommended when you need professional, maximum color accuracy or when testing materials with variable surfaces – such as glossy or textured samples. Like textile dye formulation, cosmetic shade matching, medical device color calibration, high-end printing (e.g., packaging for luxury goods), and material spectral research. learn more Understanding Spectrophotometric Parameter Measurement
