The transmission characteristics of Fabry–Perot type aluminum–magnesium fluoride–aluminum interference filters for the wavelength region 1700 Å to 2400 Å are described. Typical peak transmissions of 0.25 with bandpasses <300 Å are obtained with first-order filters on fused silica substrates. Second-order filters give narrower bandpasses. Methods of filter preparation are described briefly, and the effects of the optical properties of the aluminum reflecting layers on filter performance are discussed.
