How to use a neutral density filter

How should we use this laser mirror? Laser mirror is also a kind of mirror, which is mainly used for perspective and specially used to treat eye diseases. You must remember the method of using this laser mirror, so that you can use it flexibly for your own use, so that you can get better treatment results. Laser mirror can also improve people's vision, but if you don't know how to use it, you will get into trouble. So how to use the laser mirror?

If the incident angle and the reflection angle are perpendicular, the reflected laser will damage the output mirror of the laser or burn you! Don't try it! It's dangerous!

If it is not vertical but an obtuse or acute angle, the laser will be reflected to other places, which is also very dangerous! Because flammable and explosive items can be found everywhere now!

Secondly, it is necessary to determine which grade of laser protective goggles to use. Laser protective goggles are generally divided into two categories: imported and domestic. According to the certification, they can be divided into CE certified (CE certified) and non-certified products. According to the protection level, they can be divided into OD1+ to OD7+ levels. For details, please refer to the article "Safety Levels and Standards of Laser Glasses". For most applications, we recommend using products with CE certification and recommend choosing products with the highest protection level OD7+. Of course, for some ultrafast lasers, such as fs lasers, we still need to refer to more parameters about protection levels. Thirdly, it is necessary to put forward visible light transmittance requirements for laser protective goggles based on the working environment. Because laser protective goggles have good protection against lasers, but they also block some visible light. Most users hope to obtain a higher visible light transmittance, such as VLT>50%, so that it is convenient to directly observe the laser experiment imagination or laser processing process without adding an auxiliary light source; there are also a few users who require a lower visible light transmittance. For example, in some occasions where visible light is too strong, it is recommended to use a model with a transmittance of <50% or even <30% to achieve the best effect of eye protection.

Now after our introduction, do you still have any questions about the use of this laser mirror? Do you think that the use of this laser mirror is actually very simple? If you know how to use it, then there will be no bad troubles in the future. This laser mirror is a modern technological development and also proves the pride of us Chinese. If you don’t know how to use it, then it is best to use it with the cooperation of professionals.
