Noun(1) measuring instrument for measuring the luminous intensity of a source by comparing it (visually or photoelectrically(2) photographic equipment that measures the intensity of light
(1) When we measure the luminous intensity of a lamp with a photometer , for example, the lamp current and color temperature are quantities of the measurement equation.(2) At least 500 cells from plasmolysed and control cells were compared, using the photometer coupled to the Zeiss Axioplan microscope, which converts fluorescence intensity to exposure time for photomicrography.(3) Spectral reflectance properties were measured using flash photometry between 300 and 700 nm.(4) AERONET is a global network of more than 100 sun photometers that measure the amount of sunlight absorbed by aerosols (fine particles in the air) at wavelengths from ultraviolet to infrared.(5) Creatinine concentrations in serum were assayed photometrically with standard test combinations.(6) Sun photometers measure how difficult it is for sunlight to pass through the Earth's atmosphere as it interacts with pollution particles, which reduce the amount of light and energy reaching the Earth's surface.(7) The protein concentrations were measured photometrically , using the extinction coefficients given in Table 1.(8) In a related test, the Florida Solar Energy Center also evaluated the influence of different photometric control sensors.(9) We have performed side-by-side comparative measurements of solar-UV radiation with spore dosimetry and spectral photometry in several campaigns held at four sites in Japan and Europe.(10) The initial comparison with spectral photometry at Tsukuba Aerological Observatory showed that these two types of the measurement were remarkably concordant in general, but there existed some variability and divergence.(11) The Lux is a photometric unit, rather than a radiometric unit, which means that it takes into account the basic physics of energy and radiation, but also includes the physics of the human eye.(12) Total tropinone reductase activity was measured photometrically by NADPH consumption with tropinone as substrate.(13) After all, the stars of the best forensic science shows are often the equipment - DNA sequencers, mass spectrometers, photometric fingerprint illuminators, scanning electron microscopes and the like.(14) This cannot be a simple application of the photometric and radiometric test methods used for other conventional light sources, for several reasons.(15) Chlorophyll concentration was analysed photometrically at 652 nm after Arnon.(16) In this study, the consequences of finite excitation flash duration are analyzed using computer simulations, and a method for the recovery of phosphorescence decay times from complex photometric signals is presented.
