TīmeklisLike intensity, radiance can vary with the direction from the object to the observer. (An object that has constant radiance over all directions is called lambertian. A very matte piece of paper and the surface of a fluorescent light tube are good approximations of lambertian objects.) Figure 2. Tīmeklis2024. gada 11. apr. · The intensity of fluorescence increased with increasing concentration. Moreover, the concentration of Bi 3+ ions within a certain range can be quantitatively analyzed by a calibration curve. By adding different ions to the sensor, the stronger emission intensity resulted in a great selectivity for Bi 3+ ions in the co …

Tīmeklis2015. gada 26. jūn. · These lines indicate the light distribution and intensity from various angles. The solid line indicates the frontal view (C0/180), the dotted line the side view (C90/270). The shape of both lines is usually about the same for most lamps. In the example below the two curves overlap. You can see why in the 3D chart.
