The amount of light it collects depends on the area of the objective.

它收集的光的数量于物镜的面积。

I snapped the first slide into place under the microscope and adjusted it quickly to the 40X objective.

我啪的一声把第一张玻璃片到了显微镜下面合适的位置，并迅速调整到了40倍物镜。

First, the objective lens, often considered the heart of the microscope.

首先，物镜，通常被认为是显微镜的心脏。

The projector lenses magnify what has already been magnified by the objective lens.

投影镜头大了物镜大的图像。

Here’s how it works: The objective lens takes incoming light rays from a distant source.

工作原理如下：物镜摄来自远处光源的入光线。

The objective lens takes incoming light rays from a distant source. .

物镜从远处接收入光线。

The resolution depends in part on the size of the objective; in general the bigger the telescope objective, the better your resolution is.

解析度部于接物镜的大小；一般来说，望远镜的物镜越大，解析率就越高。

A flatter, convex objective lens reduced chromatic aberration, gave a longer focal length and, for a fixed eyepiece, greater magnification.

一个更平坦的凸透物镜可以减少色差，提供更长的焦距， 并且对于固定的眼镜片来说，能获得更大的大倍率。

The objective lens then converges the light rays to form a real, flipped image inside the telescope.

然后物镜会聚 光线，在望远镜内部形成一个真实的翻转图像。

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

伽利略的望远镜让他非常感兴趣，他还建议使用凸透镜来改进设计， 无论是物镜还是大目镜。

The imprinted beam of electrons is then magnified 40 times using an objective lens and further magnified 50,000 times using a set of projector lenses.

然后，印制的电子束通过物镜大40倍，再通过一套投影镜进一步大50,000倍。

The way you get magnification is that you just divide the focal length of the objective glass by that of the eyepiece, of the ocular.

获得大倍数的方法是将物镜的焦距除以目镜的焦距。

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.

伽利略的目镜使用凹透镜，而标准折望远镜的物镜和目镜都使用凸透镜。

Now that we have a beam of electrons, we'll explore the magnetic lenses of which there are essentially three sets, the condenser, the objective, and the projector.

现在我们有了电子束，我们将探索磁透镜，基本上为三组：聚光器、物镜和投影透镜。

After all of the like terms cancel out, you’re left with a magnification equation in terms of the focal lengths of the objective lens and the eyepiece.

在所有同类项抵消后，你将得到一个以物镜和目镜的焦距表示的大倍率公式。

And at the same time, people often put, especially if they were doing direct observation of the sunspots, they put colored lenses on top of the object glass.

同时，人们通常会在物镜上置有色透镜，特别是当他们直接观察太阳黑子时。

The object is placed just beyond the focal point of the objective lens, so light rays again form a flipped real image on the other side.

多。 物体被置 在物镜焦点之外，因此光线再次 在另一侧形成翻转的实像。

The original subtended angle is the subtended angle of the unaided eye – the angle between the center of the objective lens and the height of the real image.

原始张角是未使用辅助工具的眼睛的张角——即物镜中心与实像高度之间的角度。

It consisted of an objective lens on the end closest to the object and an eyepiece at the other end, which magnified the image produced by the objective lens.

它由最靠近物体一端的物镜和另一端的目镜组成，它大了物镜产生的图像。

After all of the like terms cancel out, you're left with a magnification equation in terms of the focal lengths of the objective lens and the eyepiece. .

在所有类似的项抵消之后，就物镜和目镜的焦距而言，您会得到 一个大倍率方程。
