Langlada: The purple light lamp can not only inspect the banknotes, but also can inspect Jade jewelry
Langlada developed a new type of money detection lamp: ultraviolet Linear lamp.
So as to greatly reduce the error rate of manual judgment and improve work efficiency.
The working principle of the fluorescent detection of the banknote detector is to detect the paper of China RMB. It is to use the light source of the ultraviolet lamp to illuminate the sports banknote and use the silicon photocell to detect the fluorescent reflection of the banknote at the same time, so as to distinguish the authenticity of the banknote. In order to eliminate the interference of ambient light on the identification of counterfeit goods, a set of color filters with the transmission wavelength consistent with the fluorescent reaction wavelength of counterfeit money must be installed on the surface of the silicon photocell.
In fluorescence detection, two problems should be paid attention to:
1. Detects the shading of spaces. External light entering the detection space will cause false alarm;
2. Dust prevention of ultraviolet light source and photocell. There is a large amount of dust in the counting process, which will weaken the detection signal when adhering to the surface of the light source, resulting in missing reports.
