Expanding the lineup of machine vision lenses for inspections and measurements at production lines

FUJINON HF-XA-5M series of high-resolution lenses deliver 3.45µm pixel pitch (equivalent to 5MP) on a 2/3-inch sensor with compact design

February 14, 2017

FUJIFILM Corporation (President: Kenji Sukeno) has announced that it will launch the FUJINON HA-XA-5M series of machine vision lenses for use in inspections and measurements at production lines. The new high-resolution lenses are compatible with a 2/3-inch sensor with a 3.45 µm pixel pitch* (equivalent to 5 megapixels).
The FUJINON HF-XA-5M series features “4D High Resolution”**, which mitigates resolution degradation even when changing a working distance or aperture value. The lenses' compact design accommodates installation at a variety of conditions at production lines. The series is available in six models of various focal lengths, allowing users to choose the optimum model according to their usage.

At manufacturing facilities, a machine vision system is generally installed to capture and recognize images of production lines, and automatically position, measure and inspect materials and components. The demand for machine vision systems is projected to grow as manufacturers continue to embrace more and more automation and labor-saving at production lines.
Amidst growing market demand for greater production efficiency and stricter quality control, manufacturers, which must carry out product inspections and measurements at production lines in varying conditions, are looking for higher image-recognition accuracy and more compact form-factor when choosing a machine vision system. This has boosted market needs for lenses, which represent the initial point of receiving image data, that offer advanced resolution performance and compact design at the same time.

The FUJINON HF-XA-5M series offers high-performance prime lenses, compatible with the industry-mainstream 2/3-inch sensor with a 3.45 µm pixel pitch (equivalent to 5 megapixels) at the working distance of 50cm, which is the most frequently-used distance among users***. Even in other conditions, the lenses' “4D High Resolution” function, mitigates resolution degradation when changing a working distance or aperture value. It maintains their high resolving power of no less than 4.4 µm pixel pitch (equivalent to 3 megapixels) on a 2/3-inch sensor from the image center to all corners. This function perfectly matches when you want to set the aperture wide open to achieve a faster shutter speed. The lenses' compact form factor accommodates installation versatility, allowing users to, install a lens closely to an inspection object in an inspection apparatus with space constraints.

Tapping into the optical technologies and precision processing and assembling technologies nurtured over many years, Fujifilm offers a wide range of lenses for the age of high resolution digital imaging, including broadcast lenses and security camera lenses. In the machine vision field with strong growth potential, Fujifilm is committed to delivering an extensive product lineup, perfected in pursuit of high performance, high image quality and high product quality.

1. Product names, focal lengths, release date and pricing:

Product name Focal length Price
FUJINON HF6XA-5M 6mm Open
FUJINON HF8XA-5M 8mm
FUJINON HF12XA-5M 12mm
FUJINON HF16XA-5M 16mm
FUJINON HF25XA-5M 25mm
FUJINON HF35XA-5M 35mm

2. Main features:

(1) Unique “4D High Resolution” performance to deliver edge-to-edge sharpness under a range of installation conditions

  • Delivering high resolution of 3.45 µm pixel pitch (equivalent to 5 megapixels) on a 2/3-inch sensor at the working distance of 50cm, which is the most frequently-used distance among users.
  • In other conditions achieving even edge-to-edge resolution of no less than 4.4 µm pixel pitch (equivalent to 3 megapixels) on a 2/3-inch sensor with “4D High Resolution” function, which mitigates resolution degradation even when changing a working distance or aperture value.

(2) Compact design for installation versatility

  • The FUJINON HF6XA-5M, with focal length of 6mm measures just 39mm in external diameter, the world's smallest*4 size for machine vision lenses of this class. The other five models are also compactly designed with the external diameter of 29.5mm, which is about the same size as general compact machine vision cameras. The entire series contributes to achieving a compact form factor for machine vision systems.

(3) Designed for installation convenience

  • Three screw holes each are provided on the iris ring (aperture) and the focus ring. Users can choose the optimum hole according to their installation conditions, providing a high level of installation convenience.
  • * Pixel pitch is an indicator of sensor's image definition capability. The unit “µm” represents the distance between adjacent pixels. The smaller the number is (i.e. higher pixel density), the higher the image definition becomes. In the case of a 2/3-inch sensor, the pixel pitch of 3.45 µm is equivalent to 5 megapixels.
  • ** 4D High Resolution is a term used to describe the distinctively high-resolution performance of FUJINON lenses, which retains high resolution evenly at the center as well as around the edges across the frame (2D) while also mitigating resolution degradation that typically occurs when changing a working distance or diaphragm aperture value (2D)
  • *** Achieving 3.45 µm pixel pitch in most parts of an image frame, although the resolution drops below 3.45 µm pixel pitch at some edges
  • *4 The smallest external diameter among machine vision lenses that are compatible with a 2/3-inch sensor, have filter thread, and have the focal length of no more than 6mm (as of February 14, 2017, according to Fujifilm data)
