1, the visible light transmittance of diamond 70 is 72%, and the ultraviolet transmittance is less than 0. 1, while the visible light transmittance of crystal 80 is 65, and the ultraviolet transmittance is less than 0.2%.
2. The diamond 70 effectively blocks heat, and more importantly, the thickness of the diamond 70 is twice as thick as that of the ordinary solar film, thus realizing the function of safety and explosion-proof, while the crystal 80 does not have this function.
