    • A semiconductor laser (41) is fixed onto a base part (22) with a submount (32) and a reference optical axis (5) is determined by the semiconductor laser (41). A groove (222) having a U-shaped section is formed on a bonding part (221), and solder (31) is applied in the groove (222) and melted and a collimator lens (42) supported by a supporting arm (61) is moved to the groove (222). A light beam emitted from the semiconductor laser (41) is guided through the collimator lens (42) to an image pickup part (7), where an image representing the state of the light beam is acquired. The collimator lens (42) is positioned with respect to the reference optical axis (5) on the basis of the image and fixed onto the base part (22) out of contact therewith, with the solder interposed therebetween. This simplifies a structure of an optical element module (11) in which the collimator lens (42) is positioned with respect to the reference optical axis (5) with high accuracy.

    • An apparatus which can correctly measure and observe optical information obtained from an object by removing a boundary diffraction wave generated from an edge of a pupil of an image pickup lens or an objective lens is provided. An image pickup lens forms a spatial image of an object on a position provided with a microlens array. A plurality of microlenses are arranged in this microlens array, for pixel-separating the spatial image. Light components from the microlenses pass through corresponding microapertures respectively, to be incident upon corresponding photoreceptors respectively for forming images. The microlenses project images of a diaphragm (pupil) of the image pickup lens on the corresponding microapertures respectively. The diameters of the respective microapertures are set to be smaller than the images of the diaphragm of the image pickup lens, so that a boundary diffraction wave which is generated from an edge of the diaphragm of the image pickup lens is blocked by a microaperture array plate and prevented from propagation to the photoreceptors.
