Yabe博士的诀窍是使用比较小的菲涅尔透镜——棱镜同心环构成的透明较薄的平面透镜。

Dr Yabe's trick is to use relatively small Fresnel lenses-transparent and relatively thin planar lenses made up of concentric rings of prisms.

一个按钮伸进该端环，并具有一个透镜盖。

A push button extends into the end ring and has a lens cap.

普通物理实验中，牛顿环干涉实验只考虑在凸透镜与平面玻璃之间形成空气薄膜下的干涉现象。

In interference experiments with Newton's ring, considered only is the interference of the air film formed between the convex lens and the plain glass.
