Ultra High Resolution Wavefront Sensors ( LIFT SERIES )

Just a few months after the debut of the “Swiss Army Knife of Optics” in the visible and SWIR wavelengths, another series of truly versatile tools demonstrates Imagine Optic’s commitment to providing the optical scientist or engineer with cutting-edge yet user-friendly instruments.

On top of combining a high-resolution mode with all the benefits that make Shack-Hartmann one of the most relied-upon technologies in optical metrology, our HASO & LIFT series embeds a fully revamped WAVEVIEW4, including the absolute tilt measurement SpotTracker technology and numerous other options.
A number of HASO series wavefront sensors will be available with a LIFT option in the coming months.

Phase Retrieval Wavefront sensing

The LIFT Series Ultra High Resolution Wavefront Sensors are based on Imagine Optic’s proprietary phase retrieval wavefront sensing technology, delivering unmatched spatial resolution for the most demanding optical measurements.
This category gathers the full LIFT product family, engineered for applications requiring fine wavefront detail analysis, absolute phase measurement, and large pupil inspection.

Unlike conventional Shack-Hartmann sensors, LIFT wavefront sensors achieve up to 16× higher spatial resolution, making them ideal for advanced optical systems where mid-spatial frequency errors and subtle aberrations must be precisely quantified.

LIFT wavefront sensors rely on phase retrieval algorithms combined with large-format imaging sensors to reconstruct the wavefront with extreme precision. The technology enables:

• Ultra high spatial sampling for detailed wavefront reconstruction

• Absolute wavefront measurement without reference optics

• Large dynamic range compatible with complex or highly aberrated beams

• Robust measurements insensitive to intensity variations and vibrations

The integration of SpotTracker technology provides simultaneous wavefront and tilt information, simplifying alignment and ensuring stable, repeatable measurements even in demanding environments.

Ultra High Resolution LIFT wavefront sensors are particularly suited for:

• High-end optical system qualification and performance validation

• Freeform optics and aspheric surface characterization

• Mid-spatial frequency (MSF) error analysis

• Large aperture and large beam testing without relay optics

• Precision alignment of optical assemblies and laser systems

These sensors are widely used in advanced R&D, aerospace and space instrumentation, laser physics, and high-precision manufacturing.

The LIFT Series includes multiple sensor models optimized for different pupil sizes, wavelength ranges, and measurement resolutions, allowing engineers to select the most suitable solution for their specific application constraints.
