Optical Structures ground, tested, and coated 4, 6-inch mirrors configured for UV use in an atmospheric ballon LIDAR system. This project was accomplished on short notice to client specifications.
Dalhousie University, CANDAC / OPAL
Optical Structures designed to client specifications, fabricated, and delivered a unique 1 meter IR LIDAR telescope for Dalhousie University, Nova Scotia, Canada. The telescope was shipped to Yellowknife, Northwest Territories, and installed at the Eureka Weather Station as part of OPAL. This facility is one of the most remote spots on Earth, located only some 300 miles from the North Pole.
Due to the remote site, our unique system was designed to be able to break down into pieces to fit into a small aircraft for transportation. The telescope was designed to also allow for assembly in an extremenly small lab space. The telescope components required no heavy equipment to remove, transport, and assemble the system once on site. Two or three man teams were able to lift, fit, and assemble the telescope with nothing more than hand tools.
OSI designed, machined, and fabricated all mechanical components in its in house CNC machine shop and welding facility. In addition all optics were fabricated on site in our own optical shop.
