Abstract An improved optical holder having a cylindrical, threaded front chamber raised from a front side thereof, a locating hole perpendicularly disposed in communication with the threaded front chamber into which a tightening up screw is threaded to hold down a focusing lens assembly in the threaded front chamber, a CCD mounting chamber at a rear side thereof in alignment with the threaded front chamber for holding a CCD (charge coupled device), a plurality of annular flanges raised one behind another between the CCD mounting chamber and the threaded front chamber for eliminating the interference of reflected and refracted light, a window aligned between the annular flanges and the CCD mounting chamber, a color filter chamber disposed between the annular flanges and the window for holding a color filter, and a mounting leg in one corner of the rear side of the optical holder for fitting into a pin hole on a circuit board on which the CCD is mounted, for permitting the CCD to be fitted into the CCD mounting chamber in alignment with the window.
An improved optical holder of the type comprising a cylindrical, threaded front chamber raised from a front side thereof, and a locating hole perpendicularly disposed in communication with said threaded front chamber into which a tightening up screw is threaded to hold down a focusing lens assembly in said threaded front chamber, the improvement comprising a CCD mounting chamber at a rear side of the optical holder in alignment with said threaded front chamber for holding a CCD (charge coupled device), a plurality of annular flanges raised one behind another between said CCD mounting chamber and said threaded front chamber for eliminating the interference of reflected and refracted light, a window aligned between said annular flanges and said CCD mounting chamber, a color filter chamber disposed between said annular flanges and said window for holding a color filter, and a mounting leg in one corner of the rear side of the optical holder for fitting into a pin hole on a circuit board on which said CCD is mounted, for permitting said CCD to be fitted into said CCD mounting chamber in alignment with said window.
