Standards FL7–FL9 represent "broadband" (full-spectrum light) fluorescent lamps with multiple phosphors, and higher CRIs. Standards FL10–FL12 represent narrow triband illuminants consisting of three "narrowband" emissions (caused by ternary compositions of rare-earth phosphors) in the R,G,B regions of the visible spectrum, which leads to ...
CIELAB is used by Datacolor spectrophotometers, including the related color difference calculations. CIELAB is used by the PantoneLive library. CIELAB is used extensively by X-Rite as a color space with their hardware and software color measuring systems. CIELAB D50 is available in Adobe Photoshop, where it is called "Lab mode". [15] [16]
If the instrument is designed to measure the spectrum on an absolute scale rather than a relative one, then it is typically called a spectrophotometer. The majority of spectrophotometers are used in spectral regions near the visible spectrum. A spectrometer that is calibrated for measurement of the incident optical power is called a ...
Diode-array spectrophotometers differed from the original spectrophotometer created by Beckman because it was the first single-beam microprocessor-controlled spectrophotometer that scanned multiple wavelengths at a time in seconds. It irradiates the sample with polychromatic light which the sample absorbs depending on its properties.
Since the human eye has three types of color sensors that respond to different ranges of wavelengths, a full plot of all visible colors is a three-dimensional figure. However, the concept of color can be divided into two parts: brightness and chromaticity. For example, the color white is a bright color, while the color grey is considered to be ...
Developed by Bausch & Lomb and launched in 1953, the Spectronic 20 was the first low-cost spectrophotometer. [5] It rapidly became an industry standard [7] due to its low cost, durability and ease of use, [8] and has been referred to as an "iconic lab spectrophotometer". [9] Approximately 600,000 units were sold over its nearly 60 year ...
