This paper discusses the efficiency of Fresnel lenses with respect to optical (reflection and transmission) losses. The efficiencies of lenses of different step widths—i.e. 2, 3, 4 and 5 mm—are the same (91·9%) in the case of reflection losses and the maximum efficiency of a lens of 5 mm step width is 95·8% with respect to transmission losses.
