Abstract

The Large Optical Test and Integration Site (LOTIS) at Lockheed Martin Space Systems Company (LMSSC) in Sunnyvale, California was designed and constructed in order to allow advanced optical testing for systems up to a maximum aperture of up to 6.5 meters in air or vacuum over a bandwidth of 0.4 to over 5 μm with a design field of view of 1.5 milliradians. Previously reported information for the LOTIS 6.5 meter diameter Collimator was based on data collected during initial testing of this device at the University of Arizona's Steward Observatory Mirror Laboratory. This paper will report progress and new results for the LOTIS Collimator as it is re-assembled and tested during its final integration into its facility at LMSSC. In addition, we will discuss Scene Projection Technology (SPT) capabilities that can be added to provide user test capabilities meeting or exceeding many of the original specifications of the Collimator, primarily in increased optical bandwidth and field-of-view. Finally, we will describe additional optical tools (e.g., interferometers and smaller collimators) that are integral to the LOTIS facility that can provide flexible optical testing options for a wide array of users.
