Abstract
The request include irradiation system with twelve LED sources arranged successively, as the source is repeated for three times over 21mm distance from each source for the same spectrum band. Flow cell is 100mm in length and can be irradiated by the three sources for each spectral band for three different location as it passes through the cell according to the presented design. The request presented aims to transfer changes in signal of light intensity to an external measuring device. The initiative mode in the irradiation process for different distance within cell length, as the active part is 72mm, while the rest represent the leading connection which ends with Teflon tube of 2mm inside diameter. The transferred signal is collected with the optical fibers into one bundle for all sources in the form of a circle with 5mm in diameter facing the PMT.
