Photometer function
WebFigure 1: A multi-purpose instrument which also serves as a photometer (luxmeter), displaying the illuminance on a desk. Photometry deals with the perceived brightness of light. Typical quantities of interest are: the total luminous flux, which is e.g. sent out by a light source, specified in units of lumens (lm),; the illuminance, which is the luminous flux … WebFeb 14, 2024 · The angular dispersion of a monochromator is defined as the change in the angle of reflection (see the angle r in Figure 7.3.7) for a change in wavelength, or dr / dλ. Taking the derivative of Equation 7.3.5 for a fixed angle of incidence (see the angle i in Figure 7.3.7) gives the angular dispersion as. dr dλ = n dcosr.
