Fujifilm’s new additions to the Fujinon Machine Vision lens lineup supporting 3 megapixels and 2/3” format

FUJIFILM Europe GmbH (President: Takaaki Kurose) has announced the release of five ‘Fujinon HF-XA Series’ high performance lenses as a new addition in the lineup for Machine Vision applications. These new lenses support 3 megapixel for 2/3” sensor format and deliver edge-to-edge even sharpness.

High resolution secures recognition accuracy

In the field of industrial manufacturing, Machine Vision systems are used to perform tasks such as positioning, classification, measurement and inspection automatically. The demand for Machine Vision systems is anticipated to make further growth with responding to the request for automation and streamlining work in the production lines. To support current market demands for more product efficiency and stricter quality management, Machine Vision systems also need to realise higher image recognition accuracy and processing speed. Therefore, camera manufacturers offer Machine Vision cameras with large sensors, high resolutions and high frame rates. The optical lenses for these cameras are also required to meet to high resolution to secure the recognition accuracy of the systems.

The FUJINON HF-XA series consists of five high performance fixed focal length lenses with focal lengths between 8mm and 35mm. The new lenses maintain their high resolving power of 3 megapixels from the image centre to all corners even when the aperture is wide open under low light conditions as well as over changing working distances. This enables a flexible usage of the lenses in versatile applications with consistent image quality. The new series comes with a small diameter measuring only 29.5mm. The small size supports the development of compact Machine Vision systems because the lens diameter is smaller than the size of many Machine Vision cameras. Furthermore, each lens has three holes for locking screws that allow for the iris and the focus ring to be adjusted from more flexible angles.

The FUJINON HF-XA series features:

• 3 Megapixel resolution: Maintain high resolution from the image centre to the corners and fully resolve at the pixel pitch of 4.4μm for 2/3” camera sensors - even with change of working distances and apertures.

• Large format: Officially support a sensor size of 2/3”. Even on larger sensor sizes of up to 1/1.2” the lenses are applicable and deliver images with a minimum of Vignetting only with 8mm focal length.

• Compact and lightweight body: All the lenses in this series offer a compact size of φ29.5mm and thereby contribute to reduce the overall system size.

• Designed for installation convenience: Three screw holes each are provided on the iris ring and the focus ring. Choose the most convenient position for affixing iris and focus even when space is limited in imaging systems.
