摘要： An optical system for viewing an object has a plurality of lenses and a main optical axis coincident with the centers of the lenses. The optical system further comprises a low magnification optical subsystem that is operative to view the object at a first magnification and a high magnification optical subsystem that is operative to view the object at a second magnification that is higher than the first magnification. The high magnification optical subsystem has a high magnification optical axis along which light rays that are received from the main optical axis are transmitted. A movable element is locatable on the high magnification optical axis and is movable in directions transverse to the axis for receiving and transmitting light rays.

摘要： The invention provides an apparatus and method for the active alignment and coupling of separate optical components consisting of a light-emitting component and a light-receiving component. It comprises first alignment means having a relatively lower optical resolving power stage that is adapted to perform coarse alignment of the light-emitting component to locate an approximate location of its point of highest intensity, and second alignment means having a relatively higher optical resolving power stage that is adapted to perform fine alignment of the light-emitting component to locate a more precise location of the said point of highest intensity. Accordingly, coarse alignment may be performed using a multi-mode fiber and fine alignment may be performed using a single-mode fiber that may further be coupled to the light-emitting component.

摘要： A die is prepared for thermal compression bonding by first aligning electrical contacts on the die to bond pads on a substrate onto which the die is to be mounted. Those electrical contacts are held against the bond pads on the substrate with a bonding tool. Partially bonding the die onto the substrate by providing heat to a portion of the die to elevate a temperature there to above a melting point of solder in the electrical contacts so as to melt at least some of the solder. Then thermally compress the whole die and heat it to above the melting point of the solder of the electrical contacts so that the solder of the electrical contacts outside the portion of the die are also melted to bond the die to the substrate.
