Optical lenses play an important role in various applications, including camera lenses, microscopes, telescopes, etc. In order to maintain its cleanliness and high-quality optical performance, ultrasonic cleaning is widely used in the cleaning process of lenses. However, sometimes the lenses cleaned with ultrasound may not be clean, which may be caused by multiple factors.

不適當的清洗劑：

Improper cleaning agents:

清洗劑在超聲波清洗過程中發揮重要作用，可以幫助去除污染物。然而，如果選擇了不適當的清洗劑，可能導致清洗后的鏡片不干凈。某些清洗劑可能不足以去除特定類型的污染物，或者可能在清洗過程中殘留在鏡片表面。

Cleaning agents play an important role in the ultrasonic cleaning process, helping to remove pollutants. However, if an inappropriate cleaning agent is selected, it may result in unclean lenses after cleaning. Some cleaning agents may not be sufficient to remove specific types of pollutants, or may remain on the surface of the lens during the cleaning process.

解決方案：

Solution:

選擇適用于光學鏡片的專用清洗劑。這些清洗劑通常具有較強的去污能力，并且不會在清洗后殘留在鏡片上。在使用清洗劑之前，確保詳細閱讀和按照清洗劑的使用說明進行操作。

Choose a specialized cleaning agent suitable for optical lenses. These cleaning agents usually have strong cleaning ability and will not remain on the lenses after cleaning. Before using the cleaning agent, make sure to carefully read and follow the instructions for using the cleaning agent.

清洗時間不足：

Insufficient cleaning time:

清洗時間過短可能不足以有效去除鏡片表面的污染物。特別是對于較為頑固的污染物，可能需要更長時間的超聲波清洗來徹底清除。

A short cleaning time may not be sufficient to effectively remove pollutants from the surface of the lens. Especially for stubborn pollutants, longer ultrasonic cleaning may be required to completely remove them.

解決方案：

Solution:

增加超聲波清洗的時間，特別是針對有較頑固污染物的鏡片。根據實際情況調整清洗時間，確保超聲波振動足夠長時間地作用于鏡片表面，以達到更徹底的清潔效果。

Increase the time for ultrasonic cleaning, especially for lenses with stubborn pollutants. Adjust the cleaning time according to the actual situation to ensure that ultrasonic vibration acts on the surface of the lens for a long enough time to achieve a more thorough cleaning effect.

清洗設備問題：

Cleaning equipment issues:

超聲波清洗器的工作原理和參數設置可能會影響清洗效果。如果設備的超聲波功率、頻率或清洗槽的溫度不正確，可能無法有效清潔鏡片。

The working principle and parameter settings of an ultrasonic cleaner may affect the cleaning effect. If the ultrasonic power, frequency, or temperature of the cleaning tank of the device is incorrect, it may not be possible to effectively clean the lens.

解決方案：

Solution:

確保超聲波清洗器的參數正確設置。參考設備的使用手冊，調整超聲波功率、頻率和清洗槽的溫度，以確保其適用于所要清洗的鏡片。

Ensure that the parameters of the ultrasonic cleaner are set correctly. Refer to the equipment manual and adjust the ultrasonic power, frequency, and cleaning bath temperature to ensure they are suitable for the lenses to be cleaned.

鏡片材料不適合超聲波清洗：

Lens material is not suitable for ultrasonic cleaning:

某些光學鏡片材料可能對超聲波清洗不適應，因為超聲波振動可能會對其造成損害或變形，從而導致清洗不干凈。

Some optical lens materials may not be suitable for ultrasonic cleaning, as ultrasonic vibration may cause damage or deformation, resulting in unclean cleaning.

解決方案：

Solution:

在使用超聲波清洗之前，了解光學鏡片的材料特性，并確保其適合超聲波清洗。對于一些敏感的鏡片材料，可以考慮使用其他清洗方法或尋求的清洗服務。

Before using ultrasonic cleaning, understand the material properties of optical lenses and ensure that they are suitable for ultrasonic cleaning. For some sensitive lens materials, other cleaning methods or seeking professional cleaning services can be considered.
