摘要： An optical glass lens set and a manufacturing method thereof are disclosed. An optical glass lens is used as an insert that is set into a cavity of a mold. By injection molding of the molded insert or press molding, an optical glass lens set with a lens holder is formed. The optical glass lens set includes at least one optical glass lens and a lens holder for fixing the optical glass lens. The manufacturing method simplifies processes and improves the yield rate. Moreover, the produced optical glass lens set is easily packaged into a camera lens, especially suitable for mini-cameras and camera phones.

摘要： A MEMS scan controller with inherent frequency and a method of control thereof applied to controllers of a MEMS mirror of bidirectional scanning laser printers are disclosed. The amplitude of the MEMS mirror is adjusted by using the inherent frequency so that scan data string is sent within effective scanning window with preset frequency of a laser source of the laser printer and a certain time interval. Thus the controller is simplified and the high precision scanning is achieved.

摘要： The present invention discloses a penta-mirror multi-reflection image scanning module including at least one light source, five reflecting mirrors, a pickup lens, an image sensor, and a frame. The reflecting mirrors reflect a light beam from a document and a plurality of reflecting mirrors reflect a light beam of the document twice or more to change the light beam direction along light path, and satisfy specific optical conditions. The total tracking length (TTL) may be adjusted through an arrangement of the distance of the five reflecting mirrors, but may not be adjusted through the angle of the five reflecting mirrors. Therefore, the present invention not only increases the field of depth by increasing the length of optical path in a limited space, but also facilitates the assembling to adapt to different tracking lengths.
