摘要：
A laser print head structure includes a laser diode array (14) coupled to a heat sink (10). A cylindrical lens element (20) is aligned with the laser diode array and bonded to the heat sink. A binary optical element (22) is then aligned with the cylindrical lens element and attached to the heat sink through the use of flexures (24). The use of the flexures permits the binary optical element to "float" in the plane of the laser diode array, thereby maintaining alignment even when the thermal expansion characteristics of the binary optical element are different from the thermal expansion characteristics of the heat sink. Anti-wicking slots (18) are provided in the heat sink at locations between the bonding points of the cylindrical lens element and the laser diode array. The anti-wicking slots, through capillary action, prevent excess adhesive from wicking along the cylindrical lens element and onto the facets of the lasers in the laser diode array. In addition, the flexures are provided with holes (28) to permit light to pass through the flexures to a light curable resin which is used to bond the flexures to the heat sink.
