Reflectance standard calibration
Did you know?
Reflectance standards are used for the calibration and verification of spectrometers. There are two kinds of reflectance standards: diffuse and specular. In practice, white and black reflectance standards are utilized for calibration. They require a similar specular or diffuse surface property to the device under test … Zobraziť viac Diffuse color standards are used to calibrate colorimeters and spectrophotometers within the range 360–830 nm. … Zobraziť viac Grayscale diffuse reflectance standards are used to establish the linearity and accuracy of reflectance spectrophotometers and colorimeters. The standards are … Zobraziť viac Fluorescence standards aid in the development of optically brightened materials, such as paper and textiles, and are widely used in the cosmetics industry. The appearance of an illuminated object is dependent upon … Zobraziť viac Wavelength calibration standards provide stable absorption spectra for validating the wavelength calibration of spectrophotometers in the ultraviolet–visible … Zobraziť viac WebPractically, the radiometric calibration target (also called calibrated reflectance panel) is a white balance card giving the reflectance properties of the card across the spectrum of light captured by the camera (i.e. Red, …
