That unblinkingly vivid Japanese sun seems the blazing focus of the glassy ocean's immeasurable burning-glass.

那一眨不眨太阳似乎就是这玻璃般大洋巨大透镜燃烧焦点。

Then with his lens he tested the hinges, but they were of solid iron, built firmly into the massive masonry.

随后，他用透镜检查了合叶，可是合叶是铁制，牢牢地嵌在坚硬石墙上。

As a result, the magnetic lenses act as convex or converging lenses.

因此，磁透镜起到透镜或会聚透镜作用。

Another important equation that’s true for both converging and diverging lenses is the magnification equation.

另一个对于透镜和凹透镜都成立重要公式是放大率公式。

This is 'What is a split diopter'.

这是“什么是分裂双透镜”。

It's because they use that wide, wide, wide bulbous lens.

是因为他们用了那种超广、超广、超广透镜。

Is the Latin word for lentil and it is indeed true that the shape of by convex lenses.

这是拉丁语中表示扁豆单词，确实，透镜形状类似于扁豆。

That initial spike glass was probably pretty short, probably only about 12 inches in length.

最初透镜玻璃可能相当短，大概只有12英寸长。

Say we have a lens that has a spherical face on both sides, known as a convex lens.

假设我们有一个具有球面镜头 两侧，称为透镜。

You might notice that the image is upside down, which will always be the case for convex lenses.

您可能已经注意到图像是上下颠，透镜总是如此。

A split diopter is a powerful tool that gives a camera an ability that not even a human eye has.

分裂双透镜是一种强大工具，它赋予了摄影一种即使人眼也没有能力。

Galileo's telescope interested him greatly, and he even suggested an improved design using convex lenses for both the objective and the magnifying eyepiece.

伽利略望远镜让他非常感兴趣，他还建议使用透镜来改进设计， 无论是物镜还是放大目镜。

This is made possible through something called a lenticular lens – a corrugated sheet in which each ridge is made up of a convex – or outward-curving – lens.

这是通过一种叫做柱状透镜东西实现，柱状透镜是一种波纹状薄板，其每个起处都由透镜（即向外弯曲透镜）组成。

There are instances in which towers were set up with a mirror inside of a dark room and sometimes with a convex lens in the aperture.

在一些情况下，人们会在黑暗房间内设置带有镜子塔楼，有时还会在开口处安装透镜。

While Galileo used a concave lens for his eyepiece, the standard refracting telescope uses a convex, converging lens for both the objective lens and the eyepiece.

伽利略目镜使用凹透镜，而标准折射望远镜物镜和目镜都使用透镜。

But the idea was that you would use a very large convex lens at the end, the object glass, not because That changes optical power, but because you're polishing only the very central part.

但想法是你会在末端使用一个非常大透镜，即物镜， 不是因为这会改变光学功率，而是因为你只打磨中央部分。

And if you work it out, you would probably have a weak convex lens with about an 18-inch focal length in combination with a pretty strong concave lens with a focal length of about 6 inches.

如果你算一下，你可能会得到一个焦距大约为18英寸弱透镜，与一个焦距约为6英寸强凹透镜组合。

There are other lens and mirror combinations in which you could have the image come into a concave mirror and the mirror could be tilted and one could look at it through a weak convex or concave lens.

还有其他透镜和镜子组合方式，其中图像可以进入凹面镜，镜子可以倾斜，人们可以通过一个较弱透镜或凹透镜来观察它。
