A 3D ray-tracing matrix method is employed for studying the effects of directional distribution of radiation sources on transmission coefficient of a transparent plate with a prismatic ridged surface. An optimized configuration is suggested for using a prismatic plate as the glazing cover of a solar collector. Promising application of the resulting properties is suggested for optimizing the efficiency of solar collectors, when their routine glassy window is replaced by a prismatic one.
