Regarding Claim 15, Liu does not explicitly teach – but Qiao does teach wherein the fifth sealed connection structure comprises a fifth sealing bulge, a fifth sealing groove and, a fifth sealing rubber ring [0025-27; 0030-35]; wherein the fifth sealing bulge is disposed on the first end surface and along the third sealing path [0025-27; 0030-35], and the fifth sealing groove is disposed on the first light-transmitting surface and corresponds to the fifth sealing bulge [0025-27; 0030-35]; or the fifth sealing groove is disposed on the first end surface and along the third sealing path, and the fifth sealing bulge is disposed on the first light-transmitting surface and corresponds to the fifth sealing groove [0025-27; 0030-35]; and the fifth sealing rubber ring is filled in the fifth sealing groove [0025-27; 0030-35]; and wherein the fifth sealing bulge is embedded in the fifth sealing groove to be seal-connected to the fifth sealing groove through the fifth sealing rubber ring [0025-27; 0030-35]; or the fifth sealed connection structure comprises a third welded connection structure, and the third welded connection structure is a welded structure formed after the first end surface and the first light-transmitting surface are welded along the third sealing path [0025-27; 0030-35]. Jun Du also teaches wherein the fifth sealed connection structure comprises a fifth sealing bulge, a fifth sealing groove and, a fifth sealing rubber ring [0049-55]; wherein the fifth sealing bulge is disposed on the first end surface and along the third sealing path [0049-55], and the fifth sealing groove is disposed on the first light-transmitting surface and corresponds to the fifth sealing bulge [0049-55]; or the fifth sealing groove is disposed on the first end surface and along the third sealing path, and the fifth sealing bulge is disposed on the first light-transmitting surface and corresponds to the fifth sealing groove [0049-55]; and the fifth sealing rubber ring is filled in the fifth sealing groove [0049-55]; and wherein the fifth sealing bulge is embedded in the fifth sealing groove to be seal-connected to the fifth sealing groove through the fifth sealing rubber ring [0049-55]. It would have been obvious to modify the system of Liu to include a connecting sheet or shell, through holes, grooves and seals to increase accuracy, while reducing dust and fog in the optical assembly.
