A comparison between a typical normalized M cone's spectral sensitivity and the CIE 1931 luminosity function for a standard observer in photopic vision In the CIE 1931 model, Y is the luminance , Z is quasi-equal to blue (of CIE RGB), and X is a mix of the three CIE RGB curves chosen to be nonnegative (see § Definition of the CIE XYZ color ...
The Hunt and RLAB color appearance models use the Hunt–Pointer–Estevez transformation matrix (M HPE) for conversion from CIE XYZ to LMS. [ 4 ] [ 5 ] [ 6 ] This is the transformation matrix which was originally used in conjunction with the von Kries transform method, and is therefore also called von Kries transformation matrix (M vonKries ).
Fluorescent penetrant inspection (FPI) is a type of dye penetrant inspection in which a fluorescent dye is applied to the surface of a non-porous material in order to detect defects that may compromise the integrity or quality of the part in question. FPI is noted for its low cost and simple process, and is used widely in a variety of industries.
ANNINE-6plus is a voltage sensitive dye with fast response (ns response time) and high sensitivity. It has been applied to measure the action potentials of a single t-tubule of cardiomyocytes by Guixue Bu et al. [ 7 ] More recently, a series of fluorinated ANEP dyes was introduced that offer enhanced sensitivity and photostability; they are ...
Color blindness changes the sensitivity of the eye as a function of wavelength. For people with protanopia , the peak of the eye's response is shifted toward the short-wave part of the spectrum (approximately 540 nm), while for people with deuteranopia , there is a slight shift in the peak of the spectrum, to about 560 nm.

The Alexa Fluor family of fluorescent dyes is a series of dyes invented by Molecular Probes, now a part of Thermo Fisher Scientific, and sold under the Invitrogen brand name. Alexa Fluor dyes are frequently used as cell and tissue labels in fluorescence microscopy and cell biology . [ 1 ]
T5 retrofit conversion is a means of converting light fittings designed to use T8 format lamps, so that they can use more energy-efficient T5 lamps. [1] This is done by electronically converting the luminaires to high frequency operation.
The reduction-oxidation sensitive green fluorescent protein (roGFP) is a green fluorescent protein engineered to be sensitive to changes in the local redox environment. roGFPs are used as redox-sensitive biosensors.
