Paper Abstract

A wide-field ultraviolet lens was developed under a contract from the Massachusetts Institute of Technology Center For Space Research in support of the NASA High Energy Transient Experiment (HETE). This 35 mm f/2.5 seven element lens operates over a broad portion of the near-ultraviolet spectrum and over a 52 degree field of view. Operation at cryogenic temperatures required that the lens system exhibit minimal change in focus with temperature. Aluminum was selected as the lens barrel material based on athermalization issues and the desire to minimize weight. Elastomeric bonding of elements into subcells was used for assembly along with a single adjustable airspace to compensate for tolerances.
