25mm C-Mount lens for up to 1.2" sensors such as IMX541

CIL554 is a 25mm C-mount lens for 25MP imaging on 1.2" sensors like the IMX541. The aperture adjusts from F/2.6 to F/16. The 19.4mm image circle covers the full 1.2" format at 2.74µm pixel pitch, so you get 25 megapixels of usable resolution edge to edge.

Distortion is -0.09% from rectilinear, which is essentially zero in practice. That matters in metrology, PCB inspection, and flatness measurement because the lens is not adding meaningful geometric error. The field of view is 52° at 19.4mm, which is a practical balance between magnification and coverage from 150mm to infinity. You can check exact coverage at field of view calculator

The lens uses an all-glass optical design, weighs 78g, and includes an M30.5x0.5 front filter thread for standard machine vision bandpass and polarization filters. The lower weight also helps on robotic arms and gantry systems where payload matters.

The C-mount interface uses 17.526mm flange distance and fits standard industrial C-mount cameras directly. The 25mm focal length is a good middle ground when you need moderate magnification and a comfortable working distance.

The lens is in stock and ships same day from San Diego for orders before 12 PM PST. Commonlands optical engineers are available for application support and volume pricing. You can contact us directly.
