White collar's xenon light-emitting tube keychain
High end souvenirs for company activities！
Product features: very small, high energy, long duration, this is the energy from the universe.
Product material: titanium alloy shell
Note: titanium is almost the only non-toxic and environmental protection metal, light and hard. Because titanium is too expensive, it was mostly used in aircraft structure, aircraft, medicine and other high-tech fields. With the improvement of people's quality of life, titanium is gradually used to make household products for the benefit of human life. TC4 titanium alloy has a series of advantages such as excellent corrosion resistance, small density, high specific strength, good toughness and weldability. It is an excellent representative of titanium alloy. TC4 titanium alloy is used to protect the product, avoid the fragile plastic shell, and increase the quality of high-grade products.

Physical meaning of the formula of Lambert's Law: when a beam of parallel monochromatic light passes through a uniform and non scattering absorbing substance vertically, its absorbance A is directly proportional to the concentration C of the absorbing substance and the thickness B of the absorbing layer, while its transmittance t is inversely related to C and B.
Lambert's law mathematical expression:
A is the absorbance, t is the transmittance (transmittance), is the outgoing light intensity (I) than the incident light intensity (I0)
K is the molar absorption coefficient, which is related to the properties of the absorbing material and the wavelength λ of the incident light
C is the concentration of light absorbing substance, unit: mol / L, B is the thickness of absorption layer, unit: cm
