[Television cytophotometer based on the principle of summation selected on given levels of optical density].

A method of cytophotometry and the apparatus for its realization are described. The object with heterogenous distribution of the dye stuff is represented as a set of areas with different optical density with following summation of these areas. The apparatus is assembled on the whole of the industrial serial instruments. The identify of measuring results obtained with a two-wave cytophotometer and with the one described here is shown.
