本論文是採用美國專利USA PATENT 4818083 共14片，拿掉倒數第二片平板玻璃後在第十三片之後插入一個鏡片以改善像差，搭配現在主流的五倍光學變焦、半視角30度為基礎進行優化，接著對四群變焦軌跡公式進行推導並繪製，最後再執行公差分析，以完成一個四群五倍光學變焦、1200萬畫素、鏡頭長10公分、成像品質良好的光學變焦鏡頭。 ;As the digital technology production towards to light and thing feature, there will be an opportunity for bridge camera to replace SLR cameras on the market. The camera lens is an important part for bridge camera; thus, the design of the camera lens becomes particularly important.
The thesis is major on discus about to improve the lens aberration from USA PATENT 4818083. To improve the lens aberration from USA PATENT 4818083, take of the penultimate lens of total 14 pieces, and plug in a lens after the 13th. The plugs in lens pair with mainstream five times optical zoom and 30 degrees of half angle technology to optimization the basis. Continually, derivation and draw four-group traction formula to perform tolerance analysis. Result in a four-group five times optical zooms, 12 million pixel, and 10 cm batter image and quality optical zoom lens.
