Abstract: The present invention is a symmetrical heat sink module with a heat pipe for spreading of heat, comprising a first and a second sets of fins each with a first and a second heat dissipation areas where the first and the second heat dissipation areas each comprises corresponding concave parts; a curved heat pipe between the concave parts with the bottom being convex out of the bottom of the first and the second sets of fins; and a base at the convex bottom of the curved heat pipe. Accordingly, the first and the second sets of fins are corresponding to each other so that the heat sink module obtains larger heat dissipation area and the function of two-side dissipation to achieve better heat dissipation efficiency.

Abstract: A glass disk substrate inspection tool uses a polarized laser beam that is directed to the first surface of the disk substrate at Brewster's angle and is then transmitted through the disk substrate to a light detector that generates a signal representative of the intensity of the light received. Because the light polarized parallel to the plane of incidence, i.e., the plane formed by the line of the incident beam and a line perpendicular to the surface of the disk substrate, is completely transmitted, there is no surface reflection at either the first or second surfaces of the disk substrate. The polarized beam is directed by a first rotating scanner to the input of a telecentric lens assembly that provides an output beam parallel to its optical axis as the beam is being scanned. The beam is then directed by a first fixed mirror to strike the first surface of the disk substrate at Brewster's angle as the beam is scanned along a line across the first disk surface.
