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 ... WebJul 12, 2024 · This is because the photopic filter in most photometers does not seamlessly match the CIE V (λ) function correctly. This incorrectness is expressed as its f1’ value. LEDs, cathode-ray tube phosphors, and discharge lamps are highly saturated sources, so can pose issues because their narrowband spectra differ largely from the broadband ...
