IR Imaging with Infrared Interferometers

There are numerous different applications for optical imaging. Development, final alignment, and qualification depend on testing at the system’s design wavelength.

These applications benefit from testing at design wavelength with an infrared interferometer system, including night vision, IR, and thermal imaging systems for aerospace and defense, lithography subsystems, remote sensing telescopes, and exotic material qualification.

ZYGO has long been acknowledged as the market leader in interferometric testing equipment, and it has created a variety of interferometer systems with unique features for use with NIR, SWIR, MWIR, and LWIR wavelengths.

For these wavelengths, ZYGO also develops and produces a variety of reference optics, including transmission spheres and transmission flats.

Key Features

Wide range of operating wavelengths:

NIR: 1.053 µm and1.064 µm

SWIR: 1.55 µm

MWIR: 3.39 µm

LWIR: 10.6 µm

The infrared test system and component setup are made simpler by the at-wavelength QFAS alignment view.

With NIR, SWIR, and MWIR models, QPSI^™ acquisition technology, exclusive to ZYGO, offers accurate measurements in situations prone to vibration.

Vibration-insensitive metrology with optional DynaPhase^™ instantaneous data capture for the most challenging settings
