DFM Engineering

DFM Engineering is an American telescope and optics manufacturer founded in 1979 by Frank Melsheimer in Longmont, Colorado.

DFM engineering produced the telescope for the Asteroid Terrestrial-impact Last Alert System (ATLAS) project.

[8] ATLAS was funded by a grant from NASA and includes initially two telescopes set 100 miles (160 km) apart.

[10] The telescopes are designed to detect large near-Earth objects and identify those which threaten to impact Earth.

[12] MCAT is designed to look for space debris, with a wide (41 degree) field of view, f/4 optics, and 1.4 m aperture.
