Large Aperture Systems

Expanded apertures for large format optics metrology

24 Large Aperture Interferometer System
24" Large Aperture Interferometer System

ZYGO's horizontal-axis beam expanders increase the native aperture size of a 4” interferometer to 12”, 18”, 24” or even 32” enabling the precision of interferometry in large format optical component and optical system qualification.

Horizontal large aperture systems offer the unique capability to maintain two independent metrology channels; one of the native 4” interferometer aperture, and the other an expanded beam up to 32”, enabling the flexibility of two interferometers in one.  When configured with the proper accessories the Large Aperture Systems can be used to measure both surface form and transmitted wavefront quality.
