Zygo Qualifire Series: Stable Zoom

Building on Success… Zygo's NEW Qualifire® Laser Interferometer

Zygo’s Qualifire represents a leap forward for laser interferometers by providing solutions to known challenges for instruments of this type.

In this episode we showcase Zygo's new feature Stable Zoom on the Qualifire 1.2+. This novel zoom method provides a stable optical alignment so that there is no shift in focus or image centering from 1X to 3X zoom. Because the optical system is diffraction-limited at all zooms, the Instrument Transfer Function (ITF) is also greatly improved making it easier to quantify mid-to-high spatial frequency features. Because there is no shift in image focus or centering when system magnification is changed, system error subtraction can be maintained for all zooms without loss of fidelity.
