HF818-12M Description


(1) Advanced optical performance suitable for the top-of-the-range series

When the iris (aperture) is set at the orange F4 marker on the lens barrel, the HF-12M series delivers the resolving power greater than 2.1µm pixel pitch on a 2/3-inch sensor (equivalent to 12 megapixels) *5.
The HF-12M series is capable of maintaining ultra-high definition with a 2.7 µm pixel pitch within the whole frame area. Each pixel with high optical performance enables stable checking of product dimensions and appearance.
  *5 At the working distance of 50cm

(2) Delivering edge-to-edge sharpness under a range of installation conditions with FUJINON lenses’ unique “4D High Resolution” performance.

General machine vision lenses share the issue of resolution degradation when the working distance or aperture is changed. The HF-12M features FUJINON lenses’ unique “4D High Resolution” performance. It maintains a high level of consitent image sharpness at the center as well as around the edges, while mitigating resolution degradation that typically occurs when changing a working distance or aperture value. This enables the consistent delivery of high-resolution images under a wide variety of installation and shooting conditions.

(3) Ease of installation and high reliability

Despite being high-resolution lenses with 2.7µm pixel pitch, all the five models come in a compact form factor with the external dimension of just φ33mm. This allows installation flexibility even in manufacturing facilities with space constraints.
General machine vision lenses use iris and focus locking screws with a head protruding out from the lens body, potentially causing interference within the machine vision system. The HF-12M series come with regular locking screws as well as headless compact screws, which can be countersunk into the lens body to minimize interference with the machine vision system, thereby increasing flexibility in system installation and design.
The lenses are built with a metal barrel for durability and robustness.
