Figure 3
(a) The structure of a copper foil with a chemically etched mesh is shown. The hole, track and thickness dimensions are 400 µm, 100 µm, 100 µm, respectively, for collimator-S and 1000 µm, 125 µm, 125 µm, respectively, for collimator-L. (b) The collimator is clamped by four screws and is then placed directly over the CCD sensor. The foils have been tightly aligned to within an error of 25 µm.
