Two EUV Filters that Were Used in a Space Flight

Caption

Two EUV filters that were used in a space flight. The wrinkly looking filter on top is made of zirconium; the smoother bottom filter is made of aluminum. Each filter is extremely thin - a fraction of the diameter of a human hair - and about 1.4 mm wide by 4.5 mm long, roughly half the size of a very flat Tic Tac.
