本論文提出手機相機顯微鏡的鏡頭設計，共分為三個部分，分別是物鏡、目鏡與相機，設計完後再匹配在一起。物鏡是5X放大率及NA等於0.25，目鏡為20X放大率，將物鏡目鏡和合而成100X放大率的顯微鏡，可單獨使用來觀察物體。相機為一個F/# 2.8 視角30度的300萬畫素鏡頭，與顯微鏡集合後，可拍攝顯微鏡觀察到的物體。 最後完成設計其顯微鏡總長度為77mm有達到可攜式搭配手機相機使用最初設計的目的。 ;The design of the cell phone camera microscope is introduced in this dissertation. There are three parts in this design; an objective, an eyepiece and a camera. Finally, combine objective, eyepiece and camera to form one system. The objective magnification and NA are 5X/0.25. The eyepiece magnification is 20X. By combining, we can design a 100X microscope system, it can be operated individually to observe the object. The camera is designed with F/# 2.8, half view angle of 30 degrees, and 3.0 megapixels. To combine camera and microscope, it can record the image. The total length of the microscope is about 77 mm. That accomplish the purpose of being portable and combining the cell phone camera.
