For every Tibetan who loves coins and stamps, having a right-hand man is essential. Among the many auxiliary tools, the purple light identification lamp is undoubtedly one of the most dazzling secret weapons. It is not only a magic weapon in the hands of senior players, but also an important step towards specialization for beginners.

Modern technology has given the purple light identification lamp powerful functional support. Its core principle is to use the phenomenon that specific substances emit fluorescence under ultraviolet radiation to distinguish. Through careful observation of paper fibers, ink composition and anti-counterfeiting marks, genuine and counterfeit products can be quickly and accurately distinguished. This is especially important for those valuable historical relics.

However, mastering the correct method of operation cannot be ignored. First, adjust the angle of the light source to obtain the clearest effect; then wait patiently for a few seconds until the measured object is completely exposed to ultraviolet rays before judging. In addition, care should be taken not to look directly at the bright light for a long time to avoid eye injury.

An interesting experience of a new philatelist is worth mentioning. He was about to buy a rare set of commemorative stamps but had doubts. So he used the small purple light lamp he carried with him to carefully check every detail. It was eventually discovered that there was a slight difference in one of them, thus avoiding an economic loss. This shows the huge energy behind the small instrument.

The various types of purple lights currently on the market have their own advantages, but there are also certain limitations. Although some high-end models have a variety of wavelength switching options, they are expensive and large in size and inconvenient to carry. However, the low-cost version often reduces the recognition accuracy or even misses the detection of important feature information due to insufficient power. Therefore, consumers in the purchase process must consider their own needs and budget range to make an informed decision.

In order to ensure the stability and accuracy of long-term use, it is necessary to do related nursing work regularly. For example, wipe the surface of the lens in time after each use to prevent dust accumulation from affecting the transmission efficiency; replace the aging lamp at regular intervals to ensure that the output intensity is always in an ideal state.

All in all, an excellent purple light identification lamp is as precious as the key to the unknown world. I hope every friend can find a product that suits him and go further and further on this fun and challenging road.
