Aerospace and defense contractors rely on 4D dynamic laser interferometers for accurate measurement of optics, optical systems and structures. 4D's vibration-insensitive interferometers play a critical role in space-based telescope programs. These systems make environmental chamber testing (at cryo-vacuum temperatures and pressures) possible, helping ensure excellent performance of satellite optics upon deployment. |
