The Kaleo IR measurement station is built to make infrared lens quality control straightforward and precise. Leveraging advanced wavefront sensing technology, it measures both MTF and wavefront aberrations (WFE) in one single capture, without the need for mechanical scanning or complex alignment procedures. Designed to support multiple IR bands — including SWIR, MWIR, and LWIR — on the same bench, it provides versatile measurement for a wide range of infrared optics from small lenses to larger apertures. Its optical configuration accommodates different lens types and testing scenarios, enabling reliable output for design validation, alignment and production quality control.

Single-Shot IR MTF and WFE Acquisition

The standout feature of the Kaleo IR station is its ability to deliver modulation transfer function (MTF) and wavefront error (WFE) data in one single acquisition without the need for scanning or repeated measurements. This reduces test times and simplifies workflows — an advantage especially valuable in high-throughput labs and production environments.

Multi-Band Infrared Support

Built for infrared optics testing, the Kaleo IR supports SWIR, eSWIR, MWIR, and LWIR spectral bands on the same optical bench. Users can characterise lenses and optical assemblies operating at different IR wavelengths without changing core hardware, enabling flexible multi-wavelength metrology.

Flexible Test Configurations

The system offers multiple configuration modes — including single or double pass, on-axis or off-axis, and infinite to finite object distances — making it suitable for a wide variety of infrared optics. Whether testing standard imaging lenses or complex assemblies for optical systems, the measurement setup can be tailored to specific requirements.

High-Accuracy Wavefront and Aberration Data

By capturing wavefront aberrations along with MTF, the station provides a comprehensive picture of optical quality — including aberration maps and design comparisons. This level of detail supports fine alignment adjustments, design verification, and quality control of infrared optics, ensuring devices meet performance expectations.

Simplified Metrology Workflow

Kaleo IR’s intuitive measurement approach removes common barriers in IR optics testing. With minimal alignment and no scanning requirement, operators can quickly capture reliable data, making it suitable for both R&D labs and production settings, improving throughput and repeatability.

Infrared Optical Manufacturing & Quality Control

In industries where infrared optics are manufactured — such as thermal imaging, night-vision systems and infrared cameras — quality control is crucial. The Kaleo IR station enables accurate evaluation of infrared lenses and assemblies by capturing key performance metrics like MTF and WFE across SWIR, MWIR, and LWIR bands. This ensures components meet design tolerances and imaging requirements before integration into final products.

Aerospace & Defense Optics Verification

Defense and aerospace applications rely heavily on high-performance infrared optics for targeting, missile guidance, and surveillance systems. Kaleo IR provides the detailed measurement capabilities needed to qualify these critical optical systems, ensuring they deliver accurate imaging and align with mission specifications across extreme environments.

Automotive and ADAS Sensors

Automotive sensing technologies — such as advanced driver assistance systems (ADAS) and night vision cameras — incorporate IR optics to operate reliably under low-light conditions. Comprehensive IR optical metrology with Kaleo IR ensures sensors provide accurate contrast, sharpness and optical performance, boosting safety and reliability.

Scientific Instrumentation & Research

Research labs working with infrared imaging systems, spectroscopy equipment, or optical experiments benefit from accurate MTF and wavefront analysis. Kaleo IR supports experimental validation and design verification for novel optical systems across diverse research fields.

Industrial Inspection & Thermal Imaging

In sectors such as industrial automation and thermal inspection, infrared cameras and optics are essential for monitoring heat profiles, detecting defects or conducting process control. The Kaleo IR station helps manufacturers ensure consistent optical image quality in these mission-critical applications.
