The Large Optical Test and Integration Site at Lockheed Martin
The Large Optical Test and Integration Site (LOTIS) at the Lockheed Martin Space Systems Company in Sunnyvale, CA is designed for the verification and testing of optical systems. The facility consists of a large, temperature stabilized vacuum chamber that also functions as a class 10k cleanroom. Within this chamber on top of a vibration-isolation bench are the 6.5 meter diameter LOTIS Collimator and Scene Generator. Optical payloads are placed on the isolation bench in the chamber for testing. The Scene Generator is attached to the Collimator forming the Scene Projection System (SPS) and this system is designed to operate in both air and vacuum, providing test imagery in an adaptable suite of visible/near infrared (VNIR) and midwave infrared (MWIR) point sources, and combined bandwidth visible-through-MWIR point sources, for testing of large aperture optical payloads.
