Fujinon HF25HA-1S Lens
The Fujinon 1.5MP 25mm C Mount Lens with Anti-Shock & Anti-Vibration Technology is designed to provide low distortion, high-quality image capture in machine vision applications. The compact lens covers 2/3" sensors and features a fast f/1.4 aperture that ensures clear images in low light environments. Focus and iris adjustment are manual, and individual focus/iris lock tabs are provided to maintain set positions over time. Built-in anti-shock and anti-vibration technology highly reduces the need for these tabs because their primary purpose was to protect against changes caused by vibration. The anti-shock and anti-vibration technology helps keep both the mechanical and optical elements of the lens in their original positions to maintain consistent image quality in harsh environments that produce a lot of vibration. The new feature also helps protect the lens from damage caused by accidental falls. The lens is complete with a robust build, metal mount, and smooth focus and iris ring rotation.

Optimal Design for Compact Form Factor Cameras

Locking Holes

FUJINON DF-HA-1S and HF-HA-1S series lenses come with locking holes for the iris as well as for the focus. They are located on the lens barrels to provide additional flexibility. Included thumbscrews provide an easy way to lock the focus and iris in place. Note: Included thumb screws can be replaced by set screws to prevent tampering.
