As one of the visual inspection tools, the industrial endoscope is mainly transmitted to the host display through the front-end probe through the lens pipeline. It is a kind of precision instrument, and every part is carefully selected. Therefore, as a purchaser, we should pay attention to the judgment methods and precautions of the industrial endoscope, Convenient and better choice of a high quality and low cost industrial endoscope equipment.

工业内窥镜主要有三部分组成，一部分，是镜头部分，就是管线的顶端有一个金属固件，里面就包裹着传输用的摄像头，这里面学问很大，现在详细说下：

The industrial endoscope is mainly composed of three parts. The first part is the lens part. There is a metal firmware on the top of the pipeline, which is wrapped with a transmission camera. There is a lot of knowledge in it. Now let's talk about it in detail

1、CMOS传感器比CCD传感器快速，CMOS转换数据要比CCD传感器要快10到100倍，这样可以在同一时间内，CMOS可以记录更多的帧数。这样可以很方便的做变速拍摄，例如快动、慢动、升格、降格；

1. CMOS sensor is faster than CCD sensor, CMOS conversion data is 10 to 100 times faster than CCD sensor, so that CMOS can record more frames at the same time. This can be very convenient to do variable speed shooting, such as fast, slow, upgrade, downgrade;

2、CMOS的感光度比CCD低的多，CMOS传感器是一种通常比CCD传感器低10倍感光度的传感器。这就导致了CMOS成像能力的要低的多；

2. The sensitivity of CMOS is much lower than that of CCD. CMOS sensor is usually 10 times lower than that of CCD sensor. As a result, the imaging capability of CMOS is much lower;
              

3、CMOS可以降低摄像机的尺寸，CMOS传感器可以将所有逻辑和控制环都放在同一个硅芯片块上，可以使摄像机变得简单并易于携带，因此CMOS摄像机可以做得非常小。

3. CMOS can reduce the size of the camera. CMOS sensor can put all logic and control loops on the same silicon chip, which makes the camera simple and easy to carry. Therefore, CMOS camera can be very small.

其次是管线部分，这里讲述的主要是工艺方面，市面上很多2mm管线，主要在于是否可以有较高的工艺水平，能否把4根牵引线，一根传导线合并到一个线管内，这就需要一定的工艺水平，因为现在没有哪一个机器是可以合成这种管线的，所以需要人工装，所以难免会有所质量问题，比如线容易断，或者信号线中间断了，导致无图像，或者方向旋转不了，或者前端亮度过低，看不清楚内部情况等，所以采购检测工业内窥镜或者选择工业内窥镜还需要看对方工艺水平，多检测几次，基本上都能检测出问题。

Secondly, the pipeline part, which is mainly about the technology. Many 2mm pipelines on the market mainly lie in whether they can have a higher technology level, whether they can combine four traction wires and one transmission wire into one pipe, which requires a certain technology level, because no machine can synthesize this kind of pipeline now, so it needs to be installed manually, So it is inevitable that there will be quality problems, such as the line is easy to break, or the signal line is broken in the middle, resulting in no image, or the direction can not be rotated, or the front brightness is too low to see the internal situation clearly, so the purchase of industrial endoscope or the selection of industrial endoscope also need to see the other party's technological level, and the problem can be detected by testing several times.

然后是主机了，这个主要是显示器以及功能，这个检测比较简单，只要查看说明书基本上都可以进行操作，工业内窥镜采购就只需要关注自己想要的功能，谁能做的到就选择谁的，再在做的到的基础上选择比较实惠的就可以了，现在市面上也有很多触屏的，建议还是具体问题具体分析，毕竟如果环境恶劣，触摸屏就很容易损坏或者不灵，所以按照自己的使用条件进行选择适合自己的工业内窥镜。

Then there is the host computer, which mainly includes the display and functions. The detection is relatively simple. As long as you check the instruction manual, you can basically operate it. The purchase of industrial endoscope only needs to pay attention to the functions you want. Whoever can do it will choose whose one, and then choose the more affordable one on the basis of what you can do. Now there are many touch screens on the market, After all, if the environment is bad, the touch screen is easy to be damaged or ineffective, so choose the appropriate industrial endoscope according to your own conditions.
