is there flashlight can control the wavelength of light?<\/strong> Several customers have asked this question, uv flashlight<\/a> use wavelengths to distinguish effectiveness of the flashlight, 395nm\u00a0wavelength and 365nm uv flashlight<\/a> effect will certainly vary, but there is no flashlight can control wavelength of the light. Now introduce 365 wavelength of a uv flashlight.<\/p>\n 365nm only some weak white light , in general, very little visible light , almost all kinds of authenticity products can use it , 365NM brightness , although weak, but the fluorescence effect is very clear , because the UV light is a special light source , please use it under low light environments,to have the ideal effect!<\/p>\n Uses : Check fluorescence reaction gemstone .<\/p>\n 1. Help category . Some gem on color appearance relatively close, but the fluorescence reaction yet obvious differences, can make use of ultraviolet fluorescent to points it out . For example : ruby and garnet , some green mother green, and green glass, sapphire and blue cone ore . The results are not the same is there flashlight can control the wavelength of light?

\n2. To help judge repair or bonding. The ceramic has no fluorescence under ultraviolet,if a certain part of porcelain emerge fluorescence under ultraviolet, you should consider whether or not patched , because the patch need to use glue, and most of the glue will fluoresce under ultraviolet : Some stick gem’s stick place will also fluoresce , because they may also use the glue so it is important to identify such things ! Such goods are not suggest to buy,no fluorescence under ultraviolet gem does not have identification significance. For example Hetian jade<\/p>\n","protected":false},"excerpt":{"rendered":"
