Look at what is behind the "anti-theft" is worth our reflection

[ Pacific Security Network News ]
In recent years, the protective window installed for safety has caused frequent accidents. Originally, theft prevention should be beneficial to people's personal safety. It may also become a nightmare to see a strong security window. This is a heart-wrenching rescue: a solid security window that completely isolates the hope of life. Rescuers are close at hand, and the sturdy security window blocks the fire escape route of the trapped; the children's climbing, playing, and safety barriers have become the "card window."
The installation of the security window at will, because it is a "casual" installation, not only is not beautiful, but also affects the city. Even in the event of a fire, children climbing and playing, this seemingly "beauty" "safety barrier" has become a "escape barrier", which often poses a safety hazard. The owner installed security windows for theft, anti-fall, etc., but they had a "safety" in mind, but they did not expect that this barrier is sometimes unsafe. From the back of these accidents, we deeply reflect on how the barrier to safety is “the cage of life”.
Anti-theft
It is not difficult to reflect, people's safety awareness is relatively weak, lack of emergency rescue knowledge, social security situation is worrying, the security window installation guarantees a temporary security but neglects the security risks caused by "accidents". Although some property companies have signed the “Property Management Service Agreement” with the owner, it is clearly required that the security window cannot be installed at will, but the owners have installed the security window in the wall for the sake of “safety” and the appearance is beautiful. The reason is that our people lack security and need this "window" to gain spiritual security. There is no clear legal ban on the installation of security windows, so there is also a “blank zone” in the management of the city. Therefore, people need to take care of both the installation of the security window, which can not only satisfy people's inner security, but also rationally and scientifically place the security window. Do not leave a dead space, give life a "empty", keep a safe key, and facilitate Use in an emergency.
"Safety responsibility is more important than Taishan". Today's social security issues are particularly prominent. We must always tighten the safety of this string. Relevant departments should put safety and stability in the first place, and increase the promotion of safety knowledge while fighting punishment. People's safety. Consciousness has been improved, and “inside and outside” can be secured when installing security windows. One of the key factors in the security window problem is also the consideration of theft prevention. This is due to the current situation of social security, which is worrying. Rethinking, if the public security is good, people's sense of security and happiness will increase, and there will be fewer natural security windows. It is not easy to achieve the prohibition of installation. It is necessary to increase the intensity of attacks through the “Tianwang” monitoring equipment, use the group anti-group patrol team to strengthen the night patrol density, strengthen publicity and education, timely conduct warning education propaganda, change the public security environment, and build harmony. A well-off society is bound to improve the sense of security of the broad masses of the people. The security window naturally has no market, and the barrier of life is naturally less.

Germanium Lens

Germanium Plano-Convex (PCX) Lenses feature precision diamond turned surfaces making them ideal for a variety of infrared applications, including thermal imaging, infrared spectroscopy, and remote sensing. Germanium (Ge) is popular for its high index of refraction, broad transmission range, and rugged mechanical properties. These lenses are available in 25 and 50mm diameters, uncoated, or with multiple broadband coating options.

Germanium (Ge) material feature high index of refraction (around 4.0 from 2 - 14μm), an anti-reflection coating is recommended on these germanium windows for sufficient transmission in the region of interest. Germanium is subject to thermal runaway, meaning that the transmission decreases as temperature increases. As such, these germanium windows should be used at temperatures below 100°C. Germanium`s high density (5.33 g/cm3) should be considered when designing for weight-sensitive systems. Ge properties
