Abstract

The possible utility of high-power hybrid achromatic spectacle lenses, each consisting of a contact combination of refractive and diffractive components, is considered. It is shown that such a combination can, in principle, minimize blur due to transverse chromatic aberration in high-power prescriptions such as those for aphakes and high myopes. The combination has essentially the same thickness and weight as a conventional singlet lens. Some practical problems relating to hybrid designs are discussed.

摘要

考虑了高倍混合消色差眼镜镜片的潜在用途，每个镜片由折射和衍射元件的接触组合构成。结果表明，这样的组合原则上可以将诸如无晶状体眼和高度近视患者的高倍处方中因横向色差导致的模糊降至最低。该组合的厚度和重量与传统单透镜基本相同。讨论了与混合设计相关的一些实际问题。
