WebFiber photometry is a powerful ultra-fast technique used to measure calcium, neurotransmitters, and other molecules in vivo. To use fiber photometry, genetically … These are optical instruments for measurement of the absorption of light of a given wavelength (or a given range of wavelengths) of coloured substances in solution. From the light absorption, Beer's law makes it possible to calculate the concentration of the coloured substance in the solution. Due to its wide range of application and its reliability and robustness, the photometer has become one of the principal instruments in biochemistry and analytical chemistry.

WebThe transit method can be used to discover exoplanets. As a planet eclipses/transits its host star it will block a portion of the light from the star. If the planet transits in-between the star and the observer the change in light can be measured to construct a light curve. Light curves are measured with a charged-coupled device.

WebA photometric system defines a set of optical bandpass filters for use in observations, which can be calibrated against a number of primary standard stars to ensure recordings are comparable across different observations. The system may be defined using a combination of letters agreed by astrophysicists around the world, including for example: WebThe Strömgren photometric system, abbreviated also as uvbyβ or simply uvby, and sometimes referred as Strömgren - Crawford photometric system, is a four-colour medium-passband photometric system plus Hβ (H-beta) filters for determining magnitudes and obtaining spectral classification of stars.
