We also design a novel UV collimator which makes infinite UV testing targets. It can reduce the difficulty of optical design and the machining cost, and utilize UV energy at maximum extent.

分辨率测试装置中采用非球面设计反射式平行光管，形成无穷远紫外分辨率目标，不仅减少了设计和加工成本，而且使紫外能量得到了最大程度的利用。

Some of the molecules in these fluorescent dyes are excited by UV energy, and afterwards, as the energy level within these molecules decreases, they release part of that extra energy as visible light.

这些荧光染料中的一些分子被UV的能量激活，然后随着这些分子的能量水平降低，它们就会以可见光的形式释放出一部分额外的能量。

We can think about the Lyman series, which is 1 where n equals 1. We know that that's going to be a higher energy difference, so that means that we're going to be in the UV range.

我们可以来看看Lyman系,也就是n等于,我们知道它的能量差更大,所以它在紫外光区内。

So, ideally what we did see was, in fact, it does have enough energy with the UV lamp, it wasn't a dramatic shift you saw because we didn't start very high and then it went to that stuck point.

所以，理想上我们所看到的，事实上，紫外灯没有足够的能力，因为我们没有从非常高开始,所以它没有一个特别显著的移动,然后它又回到了黏着点。

So that means we're going to need to figure out what is the energy per photon that's emitted by that UV light.

所以那意味着我们将需要,计算出从紫外光源发射出的,每个光子的能量。

So we can figure out the energy of each photon emitted by our UV lamp by saying e is equal to h c over wavelength.

所以我们可以计算出,每个从紫外光源射出的光子,也就是e等于h乘以c除以波长。
