In astronomy, a star’s color tells its story. Measuring the color of a star gives astronomers immense insights into its temperature, age and composition even from hundreds of thousands of miles away. By measuring stars’ wavelengths, you can determine their elemental makeup and main components. What Is Astronomical Spectrophotometry? Spectrophotometry refers to the process of measuring […]

Through forensic spectrophotometry, analysts can intensely study crime scene evidence using the power of electromagnetic imaging. Spectrophotometry is the process of scientifically and objectively measuring color and radio wavelengths. It is more dependable than using human eyes, and it provides reproducible results on an easy-to-understand scale. With spectrophotometry, forensic examiners can distinguish between the chemical […]

Inter-instrument agreement refers to how similar two or more spectrophotometers’ measurements are when reading the same color. A close inter-instrument agreement (IIA) signals your instruments are reliable and produce replicable results, while a poor IIA indicates your instruments are not uniform across your supply chain.  IIA has limited useability if you’re only operating one spectrophotometer, […]

Spectrophotometers use photometric range data to provide you with valuable insights into your products and help you ensure maximum quality assurance through color. At HunterLab, we understand color means everything and is essential to maintaining your brand integrity.  Photometric range refers to the range of light waves from ultraviolet to infrared wavelengths. The photometric range […]

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 […]

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 […]

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 […]
