Optics for Medical, Security, Industrial & Motion Picture
Fujinon : HF25HA-1S
Description
The Fujinon HF25HA-1S is a 25mm Machine Vision Lens with a 6.2μm pixel pitch (equivalent to 1.5 mega-pixel).
This series is replacing the HF-HA-1B series, and has the same compatibility and optical performance as its predecessor.
The Fujinon HF-HA-1S series are adapted from previous Fujinon designs to increase vibration and impact resistance, as well as allow for a compact design, with an outer diameter of only φ29.5mm.
With a focal ratio of up to F 1.2, these lenses ensures a clear image even in low light. They are compatible with sensors as large as 2/3″
Features
Vibration- and Impact resistant design
Compact Design with an outer diameter of φ29.5mm
