The Kaleo MTF Measurement Station is a fully automated optics test station built for rigorous modulation transfer function and wavefront metrology. By measuring MTF at multiple spatial frequencies, on-axis and off-axis, it provides detailed insights into how well a lens can resolve contrast and fine detail. The system also quantifies optical path difference (OPD) and other aberrations across the field of view — key parameters for optical performance evaluation. With compatibility for large field angles (up to ±90°) and high chief-ray angles (up to 50°), it maintains measurement accuracy and repeatability across a broad range of lens types and configurations.

Automated & High-Accuracy Optical Metrology

The Kaleo MTF Measurement Station delivers comprehensive lens performance metrics through automated on-axis and off-axis MTF measurements without physical targets. It captures modulation transfer function values at multiple spatial frequencies, providing an accurate depiction of how well a lens resolves contrast and detail across the image field. Integrated wavefront error and optical path difference (OPD) analysis further enrich the characterization, offering nanometer-scale insight into aberrations.

Wide Field and High CRA Compatibility

Optics with large field of view (FOV up to ±90°) and high chief-ray angles (CRA up to 50°) are fully supported — crucial for lenses used in consumer electronics, automotive ADAS sensors, AR/VR optics, and wide-angle imaging systems. This broad acceptance angle enables manufacturers to certify performance even for challenging optical designs used in modern imaging applications.

Multi-Wavelength & Versatile Lens Testing

The station supports measurements at multiple wavelengths, ensuring optical performance evaluation across different operating conditions. Whether testing visible, NIR, or other spectral regions, the system maintains consistent accuracy. This versatility makes it suitable for applications in scientific research, medical imaging optics, industrial cameras and multi-spectral optical components.

Efficient Measurement Workflow

Designed for high-throughput environments, the Kaleo MTF station combines an intuitive user interface with automated alignment and data acquisition. This dramatically reduces setup time while generating repeatable results — ideal for both R&D laboratories and production quality control lines. Its intuitive software enables post-measurement analysis, comparison to optical design files, and automated reporting — ensuring fast decision making and fewer manual interventions.

Optical Manufacturing & Quality Control

In optical component production, ensuring each lens meets stringent imaging performance criteria is critical. The Kaleo MTF station provides high-accuracy MTF and wavefront data that quality engineers rely on during component verification, optical assembly inspection, and final output qualification. Its repeatable measurements enable manufacturers to flag deviations early, reduce wastage, and improve yield.

Consumer Electronics & Imaging Devices

Smartphone cameras, AR/VR headsets and other consumer optics demand lenses that perform consistently at high resolution. The station’s ability to measure MTF across field angles helps engineers optimise lens stacks, identify aberrations, and validate contrast performance — essential for delivering superior imaging performance in highly competitive markets.

Automotive & ADAS Systems

Advanced Driver Assistance Systems (ADAS) and machine vision sensors require robust optical performance under real-world conditions. Measuring modulation transfer function and aberrations across wide angles ensures these lenses perform reliably under varying lighting and motion conditions — improving detection accuracy and system safety.

Scientific Research & Precision Optics

Research and laboratory optics — including microscopy, spectroscopy and astronomical instrumentation — require precise characterization of optical quality. The Kaleo MTF station provides repeatable and high-resolution MTF and wavefront data, enabling scientists to validate designs and ensure results meet experimental requirements.

Medical & Industrial Imaging

Medical imaging lenses, industrial inspection optics and machine vision cameras benefit from precise optical qualification before integration. The station’s robust data output supports stringent performance criteria, ensuring devices provide accurate, high-contrast imagery for diagnostics and automated inspection.
