'''<u><big>Protect CMOS sensor from dust and dirt</big></u>'''

Image sensors are packed and delivered with care taken to protect the element glass surfaces fromharmful dust and dirt. 

Clean glass surfaces with the following operations as required before use.

(1) Perform all lens assembly and other work in a clean environment (class 1000 or less). （If there are no conditions, try to find a clean space for assembly.）

(2) Do not touch the glass surface with hand and make any object contact with it. If dust or other is stuck to a glass surface, blow it off with an air blower. (For dust stuck through static electricity, ionized air is recommended.)

(3) Clean with a cotton swab with ethyl alcohol if grease or water stained. Be careful not to scratch the glass.

(4) Keep in a dedicated case to protect from dust and dirt. To prevent dew condensation, preheat or precool when moving to a room with great temperature differences.

图像传感器的包装和运输要非常小心，以保护元素玻璃表面不受有害的灰尘和污垢污染。

使用前，请按照以下要求进行清洁玻璃表面的操作。

(1)在干净的环境中(1000级或以下)执行所有镜头组装和其他工作。(如果没有条件，尽量找寻一个干净的空间进行装配)。

(2)切勿用手触摸玻璃表面，任何物体不得接触。如果玻璃表面粘有灰尘或其他物质，请用吹球吹掉 (对于静电滞留的灰尘，建议使用电离空气)。

(3)如果有油渍或者水渍，用酒精棉签擦拭干净，小心划伤玻璃。

(4)放在专用的箱子里，防止灰尘和污垢。当移动到温差很大房间时，为防止露水凝结，请预热或者预冷传感器。
