focusing lens

基本解释

The focusing lens set is designed with the related technical data of fiber and LD.
根据激光二极管和光纤的相关参数设计了聚焦透镜组。
We adopted Gaussian beam, ray tracing and vector diffraction integration together to analyze single beam spot-focusing lens antenna.

However, the pixel density of the film can be straightforwardly reduced by fabricating smaller array spacing and a smaller antenna size, as well as using a more tightly focusing lens for recording.
但是，薄膜的像素密度会由于通造更小的阵列间距和更小的晶须尺寸以及使用更精密的聚焦透镜等直接降低。

In macro mode, which can be set by pushing the zoom ring forward while depressing the macro button on the side of the lens, focusing is possible between 8 and 20 inches for close-up shooting with a maximum image magnification of 0.72X (35mm camera equivalent).

Additionally, the WG-3's category defining Digital Microscope mode and six LED lights surrounding the lens barrel enable focusing as close as one centimeter from the subject producing bright, shadow-free macro images.

聚焦透镜
The theory of the self-focusing was used to explain the damage of the silica window and the focusing lens in the target chamber in the experiment, and the solution was also presented.
此外，结合实验过程中的实际情况，对靶室的石英窗口及打靶的聚焦透镜出现的破坏现象，采用自聚焦原理进行了分析，并提出了避免产生破坏的方法。
