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. WebNov 27, 2024 · A spectro photo meter is a spectrometer that only measures the intensity of electromagnetic radiation (light) and is distinct from other spectrometers such as mass spectrometers. A spectrometer is typically used to measure wavelengths of electromagnetic radiation (light) that has interacted with a sample. Incident light can be reflected off ...
