Abstract

A phase contrast x-ray microscope has a phase plate that is placed in proximity of and attached rigidly to the objective to form a composite optic. This enables easier initial and long-term maintenance of alignment of the microscope. In one example, they are fabricated on the same high-transmissive substrate. The use of this composite optic allows for lithographic-based alignment that will not change over the lifetime of the instrument. Also, in one configuration, the phase plate is located between the test object and the objective.
