how to use UV lamp for separate color of glass
1. Principle of UV lamp
UV lamp is a light source with a wavelength of 250 ~ 400nm. Most of them use a combination of 254nm, 300nm and 365nm. Sometimes they are also called black lights. They are mainly used to illuminate items that need to be detected. Its principle is that after irradiating objects with ultraviolet rays, the objects will fluoresce, and the fluorescent colors of objects of different materials are also different. By observing the fluorescence of different colors, the material of the item can be initially judged.
2. How to use UV light to check the authenticity of glass bracelets
1. The fluorescent color of genuine glass bracelets is usually green or blue-green. Therefore, we can put the glass bracelet under a UV lamp and observe whether the fluorescent color it emits is green or blue-green. If so, it means that the bracelet is authentic.
2. If the fluorescent color emitted by the bracelet is yellow or red, you should be more vigilant. The bracelet may be fake. Because glass does not fluoresce yellow or red. It should be noted that fluorescent color is not the only criterion for judging authenticity. It also needs to be judged in combination with the texture of the bracelet and other characteristics.
3. When testing the authenticity of a glass bracelet, be sure to pay attention to safety and do not directly enlarge the glass bracelet to observe it in front of your eyes. The bracelet should be placed in a safe location and then illuminated with a UV lamp to avoid eye injury.
3. Other areas that need attention
1. Detect cracks in the glass, especially when there are cracks or damage, use ultraviolet lamp inspection. The cracks or damage will be more obvious. Of course, the damage to the glass will become more serious during the inspection.
2. When using a UV lamp to test the authenticity of a glass bracelet, first make sure that the UV lamp used is stable, reliable and has been maintained by professionals.
