Solar filters can be handheld or in the form of 'eclipse glasses'.

太阳滤光片可以用手拿，也可以制成日食眼。

But quantum dots can make color without a filter, and so they could be much, much brighter.

但是量子点可以在没有滤光片的情况下显色，所以可以变得更亮。

The key is the smartphone's camera and processing power combined with the lenses and filters located in the cradle.

该技术的关键在于把智能手机的摄像头处理能力，以及支架中的滤光片整合起来。

These devices concentrate the sun's rays and can seriously damage your filter and your eyes.

这些设备能够聚光，从而严重伤害你的滤光片眼睛。

As we rotate the first filter, you rotate through a family of distinct hues.

当我们旋转第一个滤光片时，你会依次看到一系列同的色调。

Be sure whatever filter you select is ISO certified, and check to make sure they are not scratched or damaged before use.

管你选的什么滤光片，要确保是ISO认证，使用前检查一下，确保没有刮痕，没有损坏。

There is only one way to safely look directly at the sun when it is partially eclipsed, and that is through a special solar filter.

日偏食时，只有一种方法能安全地直视太阳，就是通过特殊的太阳滤光片。

Except during totality, do not look at the sun through a camera, binoculars, or a telescope, even if you are using a solar filter.

除了日全食期间，要用相机、双筒望远、单筒望远看太阳，即使你正用着太阳滤光片。

For those without solar filters, there are simple indirect viewing methods you can use to track the progress of the eclipse towards totality.

没有滤光片，也有简单的间接观赏方法可以显现日全食出现的过程。

Viewing it through a camera, binoculars, or telescope, without making use of a special filter for the sun can cause severe eye injury, experts say.

专家说，通过相机、双筒望远（即望远）看太阳，而使用特殊的太阳滤光片，可能会导致严重的眼睛损伤。

If you don't have these filters you can still observe the eclipse by making a pinhole camera using materials from around your home.

如果你没有滤光片，你可以选择使用针孔摄像机，用一些家周围的材料就可以制作。

Which is why rotating the initial filter changes the colour you see coming out the other end.

这就是为什么旋转初始滤光片会改变你从另一端看到的颜色。

And it doesn't have to be the first filter, if you rotate that second filter, you also rotate through these various different colours.

而且它必是第一个滤光片，如果你旋转第二个滤光片， 你也会经过这些同的颜色。

This oscillation is important, because you can limit what light passes through a filter, depending on which direction its electric field is oscillating in.

这种振荡很重要，因为您可以限制通过滤光片的光，具体取决于其电场的振荡方向。

In order to see any evidence of the separation, one thing you could do is pass it all through a second linear polarizing filter.

为了看到任何分离的证据，你可以将其全部通过第二个线性偏振滤光片。

And if you look at this whole setup from the top, as you rotate one of those filters, you'll see different colors.

而且， 如果你从顶部观察整个装置，当你旋转其中一个滤光片时，你会看到同的颜色。

And the other thing I want to draw your attention to is the colour that's coming out of the tube after it passes through that second filter.

另外我要提请你注意的是，光线经过第二个滤光片后从管子中出来的颜色。

I'm sure they'll ship one, but the idea here is that OLED is a little bit dimmer than it needs to be because it has to shine the light through a filter.

我确信他们未来会推出这款产品，但是这个概念需要的OLED要暗一些，因为它必须过一个滤光片。

Well, there will be some scattering, I suppose, but then if we just look the tube, we're not applying any kind of filter to just looking directly at the tube.

- 嗯， 我想会有一些散射，但如果我们只是看试管，那我们并没有使用任何滤光片直接观察试管。

So, colours which happen to align very closely with that filter pass through almost completely whereas colours which end up more perpendicular to the filter pass through only very weekly.

因此，与该滤光片方向非常一致的颜色几乎完全过，而与滤光片方向更垂直的颜色则只能非常微弱地过。
