概要（Overview）

The Zygo Mark II Interferometer System* is designed for measurement problems requiring high precision, noncontact, nondestructive evaluation of specular plano or spherical surfaces in reflection, or components or systems in transmission. The key modules in the Interferometer System consist of the Mark II Mainframe and the Video Monitor. An optional Model VP-2 Video Printer may also be added to provide hard-copy output. Each of the system modules is described in detail in this section.
