本文讨论了菲涅耳透镜在光学(反射和传输)损耗方面的效率。对于反射损耗,阶跃宽度为2、3、4和5 mm的透镜的效率相同(91.9%),对于传输损耗,阶跃宽度为5 mm的透镜的最大效率为95.8%。
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.
