HF-12M Series - Technologies

• Misalignment of the axis of the lenses during the manufacturing process prevents the intended performance from being exhibited. It is crucial to align the axis of the lenses to the micrometer level during its manufacturing process.
   
• The HF-12M series realized high-resolution consistent all the way to the periphery of the image. This is accomplished by detecting all lens core misalignment using proprietary inspection equipment of Fujifilm manufacturing technology and aligning the whole lens constructions with micrometer level adjustments.

• Fujifilm’s proprietary manufacturing technology is utilized by applying the precision technology needed for manufacturing broadcast lenses that require high-dimensional and consistent qualities, to the manufacturer of miniature lenses such as camera modules for mobile phones.

• In the case of ordinary machine vision lenses, the optical axis shift occurs when shock moves lenses from their initial position and it affects the lenses ability to provide highly precise measurement.
  Fujifilm’s unique mechanical design^*1 paired with FUJINON Anti-Shock performance suppresses the optical axis shift less than 10um^*2 even when shock up to 10G^*3 is present.

Axis shift when given repeated shocks

• The ordinary machine vision lenses have problems of toughness under working environment where vibration occurs.
  FUJINON Anti-Vibration performance has passed vibration test conforming to IEC60068-2-6. This feature helps to keep both the mechanical and optical elements in their original position while maintaining superb resolution.

• Fujifilm original mechanical design minimizes the use of adhesive to avoid aged deterioration that can be caused by humidity and heat in the production line.
• The variable throttle mechanism does not require iris parts to be changed and allows easier installation.

• In lens design, reducing the number of lenses and forming an image by abruptly bending light that enters the lens achieves miniaturization. Distortion cannot be controlled if the lenses are only composed of the commonly used spherical lens. However, the aspherical lens can yield the same results of using multiple spherical lenses, enabling the control of distortion with far fewer lenses.
   
• Aspherical lenses require precision processing. Fujifilm can design and manufacturer aspherical lens within its own group. The precision processing required in the design stage and its mass production is realized by accurate die machining technology.
   
• The HF-12M series realizes both miniaturization and low distortion by implementing the high-precision glass mold aspherical lenses.
