WebLuminous flux Φ v is the basic photometric quantity and describes the total amount of electromagnetic radiation emitted by a source, spectrally weighted with the human eye's spectral luminous efficiency function V (λ). Luminous flux is the photometric counterpart to radiant power. The unit of luminous flux is lumen (lm), and at 555 nm, where ... WebFigure 3. The optical design of the microplate photometer heavily influences OD measurements. Detector collection window size and distance from the sample change the resulting OD values, and therefore different photometers will give different ODs with the same sample. The detected OD difference can easily be 20–40%. novacaine is what type of anesthetic

"WebFor example, photometric measurement is useful for testing with a 96 or 384 multi-probe head since all transfers can be performed and measured at the same time. Each well in a 96- or 384-well plate corresponds to a channel on the multi-probe head. Since an absorbance value is collected per well, the transfer volume can be determined per channel.
