The Kaleo MTF from PHASICS is an automated optical metrology station designed for the comprehensive characterization of compact, complex imaging lenses with wide fields of view and high chief ray angles. Built for modern optical systems used in smartphones, automotive ADAS, drones, security cameras, AR/VR devices, and other high-performance imaging platforms, Kaleo MTF enables rapid evaluation of lens quality across the full field and multiple azimuths.

As lens designs continue to become smaller, faster, and more demanding, traditional lens testing methods can be limited when measuring off-axis behavior, high field angles, and high-CRA optical assemblies. Kaleo MTF addresses these challenges by combining MTF measurement and wavefront error analysis in a single automated station. It supports both on-axis and off-axis characterization, allowing users to assess real optical performance across different field positions, wavelengths, and orientations.

This automated measurement station is well suited for both production quality control and R&D optical development. In production environments, programmable measurement sequences help improve repeatability, reduce operator dependency, and increase throughput. In research and engineering laboratories, advanced acquisition and analysis tools support deeper investigation of optical aberrations, modulation transfer performance, through-focus behavior, distortion, field curvature, and other image-quality parameters.

Kaleo MTF is particularly valuable for testing lenses with large field of view requirements up to ±90° and chief ray angles up to 50°. Its multi-wavelength capability enables characterization across selected spectral bands, making it appropriate for visible and near-infrared imaging systems. This is especially important for applications where optical performance must be validated at several wavelengths, such as RGB imaging, NIR sensing, machine vision, biometric systems, and multispectral camera modules.

Unlike target-based MTF measurement approaches, Kaleo MTF provides access to a broad range of optical performance data through wavefront-based analysis. Users can evaluate parameters such as effective focal length, f-number, image height, point spread function, relative illumination, distortion, Zernike polynomial decomposition, and optical path difference. This makes it a complete lens characterization platform for correlating measured performance with optical design expectations and identifying manufacturing or assembly deviations.

The system is designed to simplify complex optical testing workflows. Users can define wavelengths, field angles, azimuths, and repetition counts, then execute automated measurements with minimal setup. Results can be reviewed by wavelength and azimuth, post-processed after acquisition, and compared with optical design data for efficient validation. This workflow helps optical engineers and production teams quickly determine whether a lens or lens assembly meets required imaging specifications.

With its combination of automation, high-CRA compatibility, multi-wavelength analysis, and full-field lens evaluation, PHASICS Kaleo MTF is a powerful solution for manufacturers and developers of advanced miniature camera optics. It provides the precision and repeatability required to characterize demanding optical assemblies used in next-generation imaging systems, from mobile devices and automotive vision modules to AR/VR optics and compact machine-vision cameras.
