For every friend who loves collecting, it is particularly important to have a reliable "golden eye. Today we are going to introduce such a necessary artifact for Tibetan friends- purple light identification lamp . Whether it is a precious stamp or a long-standing coin, this device can quickly and accurately judge its authenticity. Its emergence not only simplifies the traditional identification process, but also provides a more convenient and efficient way for enthusiasts to protect their investment value.

So what exactly is purple light ? In fact, this is a professional instrument based on the principle of ultraviolet light. When we place the object to be detected at a specific wavelength, if the object contains a fluorescent substance, it will show obvious reaction characteristics (such as luminescence) under ultraviolet light. This phenomenon is widely used in currency anti-counterfeiting marks and art surface coating analysis and other fields.

After understanding the basic concepts, let's talk about how to correctly operate this magical little device for practical verification. First of all, it is necessary to ensure that the ambient light is as dim as possible in order to better observe the effect. Secondly, adjust the appropriate distance according to different materials to obtain the most ideal result display form-usually, it is recommended to maintain a spacing of about 10cm to achieve good display quality. Finally, don't forget to turn off the switch in time after each use to avoid excessive battery consumption!

Of course, there are many different types of products available for consumers to choose from. Here, I would like to recommend you several options with high cost performance:
the first model has the function of multi-gear adjustment, which can flexibly switch the intensity level according to specific needs so as to adapt to more scenarios and applications;
the second one adopts lightweight design, which is very convenient to carry and suitable for friends who often go out to participate in exhibitions and exchanges;
The third category is tailored for high-end users. It supports data analysis and processing by connecting computer-side software to further improve overall performance.

Looking to the future, with the continuous progress of science and technology, the speed of upgrading is accelerated. I believe that a new generation of more powerful versions will come out soon. At that time, in addition to retaining the original advantages, innovative elements such as artificial intelligence-assisted diagnosis will be added to make the whole process more automated and intelligent, which will greatly reduce the negative impact of human error and also allow more ordinary people to enjoy the convenience brought by high-tech achievements.
