4D High Resolution

Fujinon HF-XA-5M 4D High Resolution Technology
Machine Vision Camera Lenses typically have problematic performance degradation of resolution when the focal position or aperture (f-number) are changed. The Fujinon HF-XA-5M lens family feature High Performace "4D HR" technology to minimize the effects of this degradation.

4DHR technology maintains highly consistent image sharpness from the center of the image out to the edges, while minimizing degradation of resolution caused by changes in the shooting distance or aperture. This technology delivers consistent high-resolution images under a wide variety of setups and environments.

Optimal Design for Compact Form Factor Cameras

Despite being high-resolution lenses, the HF-XA-5M series lenses are excellent for use with compact form factor machine vision cameras.

Multiple Locking Holes

FUJINON HF-XA-5M series lenses comes with three locking holes for the iris as well as three additional locking holes for the focus. They are located on the lens barrels to provide additional flexibility.
