ABSTRACT:
The present invention includes a lens holder base, a first covering element and a second covering element. A V shape trench is formed on the top surface of the lens holder base for holding the lens. Further, the trench is preferably formed to be orthogonal to the CCD. The first covering element and the second covering element are utilized for preventing the noise light from interfereing the CCD. The second covering element is a flat plane having a protrudent portion, which is connected to the first covering element. The flat plane portion of the second covering element has screws that are used to connect to the top surface of the lens holder base. An adjusting element is set on the top of the protrudent portion for adjusting the focal length of the lens set.
