Abstract: Provided is a body liquid collecting device comprising a body liquid collecting auxiliary sheet (9), and a transparent member (12) made integral with the body liquid collecting auxiliary sheet (9) and having a lens (11) for collecting laser beam from a semiconductor laser (4b) such that it is interposed between the body liquid collecting auxiliary sheet (9) and the lens (11), so that the surface of the auxiliary sheet (9) may have its surface positioned at the focal point of the lens (11). As a result, the laser beam can be collected at a predetermined portion (or the focal point portion), so that a micro-hole can be reliably formed with a relatively low laser power.

Abstract: An optical system is provided which has an optical surface capable of being selected continuously between dimensionally numbered aberrations. The optical surface has a symmetry of revolution with respect to its horizontal axis defined by the length of a horizontal perpendicular from an arbitrary point on the surface to a plane tangential to the vertex of the surface, which is represented as a function of an absolute value for the height of the arbitrary point from the optical axis. The function contains aspherical terms with real number powers which are greater than 2, but not an integer.
