4D dynamic laser interferometers play critical roles in the manufacture and test of terrestrial and space-based telescope optics and optical systems.

The world's premier large optics manufacturers rely on 4D systems to verify the shape of monolithic and multi-segment mirrors.

4D dynamic laser interferometers: accurate measurement for astronomy applications

Satellite manufacturers and integrators use 4D laser interferometers for testing optics and systems in cryo-vacuum environments, for alignment of optical systems and multi-segment mirrors, and for determining the shape and shape change of precision structures.

Behind the scenes of every major large telescope project, 4D interferometers ensure that hardware performs to the increasingly rigorous specifications required in leading-edge astronomy.
