Photometer transmission
Spectrophotometry is a branch of electromagnetic spectroscopy concerned with the quantitative measurement of the reflection or transmission properties of a material as a function of wavelength. Spectrophotometry uses photometers, known as spectrophotometers, that can measure the intensity of a light beam at different wavelengths. Although spectrophotometry is most commonly applie… WebNatural illumination (daylight or skylight—analo- gous to total and diffuse radiation) is normally meas- ured with a photometer resembling a pyranometer. Ideally, the spectral response of the sensor should be the same as that of the human eye. ... TRANSMISSION OF R A D I A T I O N B Y A W A T E R - F I L T E R A tray of water is useful as a ...
