Why Effective Bandwidth Matters
Bandwidth is an essential component to measuring spectral resolution accurately and determining the objective scientific properties of color. Spectrophotometers rely on effective bandwidth measurements to accurately give wavelength readings and assist with product quality assurance, forensic analysis, biochemical testing and more. Effective bandwidth allows analysts to measure wavelengths of testing samples by isolating narrow bands […]
What Is Spectral Range?
Spectral range is essential to measuring visible light spectrum wavelengths and giving your organization insight into its forensic test samples. With a spectrophotometer from HunterLab, you can test the spectral range of your forensic samples with unparalleled accuracy and insight. Spectral range refers to the range of color wavelengths a spectrophotometer can measure. Spectrophotometers measure electromagnetic […]
What Is Spectral Resolution?
The CIE defines the Human Visual response to be in the range of 380nm to 780nm of light and provides weighting tables so that a user can determine a color from a spectral curve by multiplying the instrument measurement at a wavelength by the corresponding Human Visual response weight at that wavelength and then summing […]
What Is a Dual-Beam Spectrophotometer?
Spectrophotometers are pieces of equipment that scientifically measure color by measuring light as individual wavelengths. In industrial and commercial settings, spectrophotometers are useful for determining product color and ensuring customer satisfaction. Dual-beam spectrophotometers allow businesses to ensure color quality control for medication, food, beverages, medical test samples and more. Today, dual-beam spectrophotometers are essential to […]
What’s the Right Geometry for Solid Opaque Colors?
Color control is essential in the quality and visual appeal of a product. However, the color matching process requires more than visual analysis. Color measurement is a quantitative analysis of the color of products that ensures colors are the same. Because many factors can influence how a color looks to the eyes, color classification systems […]
How to Test the Turbidity in Water
A liquid’s appearance and appeal to consumers are based on optical qualities like turbidity. Learn more about the meaning of turbidity and our turbidity test procedure with a spectrophotometer. What Is Turbidity? Turbidity is the measure of the clarity of a liquid to indicate the presence of suspended particles. It’s a visual feature that can […]
Food Dyes — Harmless or Harmful? Why Do We Color Food?
A food dye is a chemical substance that uses artificial color to enhance the appearance of food. Though dye may make drinks, candy and other food look better, many are concerned about adverse side effects. Learn more about why we color food and how it impacts health. The History of Food Coloring Food coloring has […]
