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=lg(1/T)=Kbc

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

郎伯比尔定律的公式物理意义：当一束平行单色光垂直通过某一均匀非散射的吸光物质时,其吸光度A与吸光物质的浓度c及吸收层厚度b成正比，而透光度T与c、b成反相关。

朗伯比尔定律数学表达式 ：

A=lg(1/T)=Kbc

A为吸光度,T为透射比(透光度),是出射光强度（I）比入射光强度(I0).

K为摩尔吸收系数.它与吸收物质的性质及入射光的波长λ有关.

c为吸光物质的浓度,单位为mol/L，b为吸收层厚度，单位为cm
