title: Construction model for microalgae photometric cell
abstract: The work assesses the efficiency of red light-emitting diodes widely used in phyto-irradiators. The article focuses on the emitting monochrome LED with an extended radiation range in a photometric cell used for determining the concentration of pigments in microalgae cultures, Spectrophotometric methods are known as the most accurate and relevant methods for assessing the concentration of pigments, having significant advantages for monitoring and controlling the process over chemical ones in term
