The problems of mobile development of optoelectronic devices (EIA) for environmental monitoring in order to ensure the safety of railway transport objects in real time at any time of the day in difficult climatic conditions, including in a thin fog, clouds, smoke. The tendency of creation of multichannel means of detection of objects in which thermal imaging, radar, television, laser and visible channels of detection with various processing of their signals can be used is used. The problem of the choice of optical material of the input window of a multichannel device is considered in detail. The presented development of a two-channel Sep with one input window allows to obtain an integrated signal and a sharper and more contrast image as a result of summation of the advantages of the visible and infrared channels and, in addition, to reduce the weight and size of the parameters and the cost of the Sep.
