ABSTRACT:
A collimator obtained by the alternate stacking of metal sheets1(40 μm thick) having holes4with a width of 2200 μm in the center thereof, and metal sheets2(10 μm thick) devoid of holes (the metal sheets1with the holes4are shown in the state in which they exist before being cut in the manner described below, the metal sheets1in the upper portion of the figure and the metal sheets in the bottom portion are not connected with each other in the finished product). The opposite sides are held by metal pressing sheets3that are 2 mm thick. These metal sheets and pressing sheets are bonded by means of diffusion bonding based on thermocompression bonding. The portions with the vertical through-holes4(40 μm×2000 μm) thus become light-transmitting portions, the metal sheets2serve as partitions between adjacent holes4,and light collimated to a width of 40 μm can ultimately pass through. A compact collimator having high wavelength resolution without wavelength dependence can thus be achieved.
