Infrared Thermal Imaging Autofocus Test System

Automated Focusing · Precision Testing · For R&D and Mass Production

As infrared thermal imaging technology rapidly expands into security monitoring, industrial inspection, and medical applications, the precision of autofocus has become a key factor in determining both image quality and temperature measurement accuracy.

According to GB/T 43249-2023, the focusing accuracy of thermal imagers must be controlled within ≤ ±5 μm.
However, traditional manual focusing methods present several challenges:

· Subjective errors – Manual judgment of image sharpness is prone to defocus and blurring.
· Limited accuracy – Simple tools lack the precision needed for high-resolution detectors.
· Low efficiency – Manual processes cannot support large-scale production.
· Poor traceability – Lack of systematic parameter records prevents quality tracking.

The Solution
The Infrared Thermal Imaging Autofocus Test System adopts precision screw drive + dual closed-loop control technology, achieving ±2 μm focusing accuracy. It automatically captures the sharpness peak of images and is equipped with a 100 cm × 60 cm adjustable temperature test chart (ambient–80 ℃). The system supports SFR, FOV, non-uniformity, and MTF testing, ensuring both R&D and production lines achieve optimal imaging performance.

Key Advantages

· High-precision autofocus: Automatic peak capture eliminates defocus and blurring.
· Strong consistency:Batch-to-batch focus deviation ≤ ±3 μm, outperforming manual adjustment.
· Efficiency boost: Throughput of 800–1000 units/day, 3–5× faster than manual methods.
· Full traceability: Records focus time, displacement, and sharpness data; supports MES integration.
· User-friendly: Intuitive HMI interface, no infrared expertise required.
· Future-ready: Compatible with high-resolution detectors and large-aperture telephoto lenses.

Testing Capabilities ：SFR(Spatial Frequency Response)、FOV(Field of View)、Non-uniformity detection、MTF analysis (with dedicated targets)
