Lens Calibration Test Card for Surveillance Camera Focus Calibration and Photography Equipment Lens Focusing Test Card
Lens Calibration Focusing Test Card
,camera Lens Focusing Test Card
The Lens Focusing Test Card is a specialized tool designed for camera lens calibration. Its core function is to assist in completing lens focus calibration, back focal length detection, and resolution verification, while also helping to troubleshoot imaging problems such as pincushion and barrel distortions. It is widely used for precision debugging in photography equipment, surveillance cameras, industrial vision systems, and other demanding scenes.
Its common design features a fan-shaped star as the core pattern, and some models are equipped with black-and-white line pairs, gradient lines, and other markings. The test patterns are evenly distributed across different areas, allowing the entire image range to be covered for comprehensive focusing performance testing.
- Lens Calibration: Assists in adjusting the camera lens, completing focus accuracy calibration across the full focus range, and resolving the problem of a lens being out of focus.
- Performance Testing: Verifies the focal length of the lens and the resolution of each area of the image, and identifies geometric distortion issues in the imaging.
- Equipment Calibration: Serves as a necessary clarity calibration tool for monitoring systems, industrial cameras, and film and television camera equipment after assembly.
A reliable calibration reference for photography equipment, surveillance cameras, and industrial vision applications — ensuring precise focus and consistent image quality.
