In order to satisfy the requirements of space X-ray surveys at home and abroad, some X-ray filters could be used in space project were manufactured. First, the transmission properties were characterized by UV-V is spectrometer and X-ray source of synchrotron radiation. The relationship between the optical properties and geographic structure of X-ray filters was studied. The results indicate that in the ultraviolet, visible, and infrared bands, the transmission decreased as the thickness of the Al layer increased. The transmission of filters, whose Al layers are deposited on one side of polyimide, is lower than that whose Al layers are deposited on both sides of polyimide. The transmission is less than 10-4 while the thickness of Al layers is 120 nm. In the X-ray band, the transmission is determined by the whole thickness of polyimide and the whole thickness of Al. The proposed filters can satisfy the present requirements of space X-ray surveys.
