The laser protective window in the laser workplace requires two important indicators. One is safe and effective protection of laser radiation. The second is that the protective window should meet the requirements of safety glass. The PMMA (acrylic, laser wiretapping blocking film quotation, English ACRYLIC) currently on the market can meet the requirements of protecting laser radiation, but the acrylic plate is very brittle and has poor impact resistance. Once it is impacted by external forces, it will become sharp The shape is broken, and splashes hurt the human body. In order to produce efficient and safe protective windows, our company has invested a lot of technical strength in research and development, and finally developed and produced laser protective windows with high laser protection grade OD6 @1064nm and safety explosion-proof grade.


Application of laser protective film in preventing laser detection and interference

Modern laser detection technology, through the emission of near-infrared laser, achieves blindness and touchlessness. Infrared laser detectors make your indoor activities unsecured: indoor speaking, there are ears outside the wall; in outdoor situations, there are eyes outside the wall.


 


The basic principle of modern laser detection is to use infrared lasers, such as lidars, to emit invisible infrared lasers into the room through windows. When the lasers pass indoor objects, they generate echoes, and then they are emitted through the windows and transmitted to the receiver. The device passes precise distance measurement, and the data obtained is processed by a computer to draw 3D images and audio.


The film absorption type laser shield (window) is composed of a laser shield and a substrate. The substrate can be selected according to user requirements, such as acrylic or glass. It can also realize self-sticking and DIY construction at the factory. The thickness can also be determined according to user requirements.

Laser wiretapping blocking film, nano-level laser blocking agent is evenly added to the window film to realize the laser wiretapping blocking function. Under the electron microscope, you can see evenly distributed laser wiretapping blocking materials. Generally speaking, the uniformity of the distribution also represents the quality of the product. The more uniform the distribution, the better the quality. Laser protective film has excellent characteristics and broad application prospects:

Appearance: Appearance is the same as ordinary film


 


[Question]: The protection level is 99% and 99.99%, only 1% difference, what is the difference?


[Answer]: The protection level is 99%, the laser transmittance is: 1-99%=1%, and the protection level is 99.99%, and the laser transmittance is: 1-99.99%=0.01%. Since the laser goes back and forth to the window (membrane), it has to undergo two absorptions. Therefore, the protection of 99% of the window (membrane) can attenuate the laser energy to 1%*1%=0.01%, that is, one ten thousandth. For a window (film) that protects 99.99%, the laser energy attenuation is: 0.01%*0.01%=0.000001%, that is, one part per billion. Therefore, the protective effect of 99% and 99.99% windows (films) differs by about 10,000 times.
