Abstract

Currently under fabrication at Optovac, Inc. are two prototype test windows (MgF₂ and LiF) to be used on the 75 mm UV MAMA detector tubes for the Hubble Space Telescope Imaging Spectrograph (STIS). The spatial and optical constraints of this instrument dictate that the thickness of the window materials be no greater than 2 to 3 mm to achieve a minimum 50 percent transmission at Hydrogen Lyman alpha (121.6 nm), and that the window must be domed to minimize optical aberrations and provide structural strength. The detector window has an input diameter of about 100 mm with a radius-of-curvature of 70 mm. The manufacturing processes involved in the fabrication of these windows will be discussed, as well as test programs (optical and structural) to be performed at Goddard Space Flight Center (GSFC).
