This paper presents the general equation to calculate the standard deviationof reflected ray error from optical error through geometry optics, applying theequation to calculate the standard deviation of reflected ray error for 8 kindsof solar concentrated reflector, provide typical results. The results indicatethat the slope errors in two direction is transferred to any one direction ofthe focus ray when the incidence angle is more than 0 for solar trough andheliostats reflector; for point focus Fresnel lens, point focus parabolic glassmirror, line focus parabolic galss mirror, the error transferring coefficientfrom optical to focus ray will increase when the rim angle increase; for TIR-Rconcentrator, it will decrease; for glass heliostat, it relates to theincidence angle and azimuth of the reflecting point. Keywords: optic error,standard deviation, refractive ray error, concentrated solar collector

Theoretical analysis of error transfer from surface slope to refractive ray and their application to the solar concentrated collector
