Wide-Angle M12 Lenses
Cover more of the scene with a compact S-mount lens. Choose the field of view on your sensor, then check edge image quality and mechanical fit.
Wide-angle coverage depends on the lens projection and the sensor’s active area, not focal length alone. Compare the lenses below, select an M12 barrel and filter option, and order samples for your camera.

Choose Coverage and Projection Together
For robot navigation or room coverage, begin with the scene your camera must see. A rectilinear design aims to keep straight lines straight. Fisheye designs use a different angular mapping to fit a wider scene onto the sensor; straight lines away from the image center can appear curved.
Software can remap a calibrated image, but the output crop and resampling affect usable coverage and detail. Compare lenses using the projection and distortion data for each design, rather than treating every wide-angle lens as rectilinear.
Check the Edges, Not Just the Center
Inspect modulation transfer function (MTF) and relative illumination across the image field at your working distance. A sharp center does not establish that the corners will resolve your target or receive enough light.
Compare the lens chief ray angle (CRA) curve with the sensor requirements. Confirm cover glass, IR filter thickness, rear clearance, and thread engagement before selecting a barrel. Test the complete lens, holder, and sensor assembly.

Wide-Angle Lens Questions
Does the Same Lens Give the Same Field of View on Every Sensor?
No. The sensor’s active width and height determine which part of the image the camera records. Lens projection and distortion determine how scene angles map to that image. Compare horizontal, vertical, and diagonal field of view for your sensor rather than using a single catalog angle without its reference format.
Is Every Wide-Angle M12 Lens a Fisheye?
No. Wide-angle describes coverage; fisheye describes a family of projections. Some wide-angle designs are rectilinear, while others use fisheye mappings. Check the individual lens projection and distortion data before deciding how the image will be used.
Can Software Correction Replace a Low-Distortion Lens?
Calibration and remapping can correct geometric distortion, but they change the output crop and sampling. They cannot recover detail that the lens did not resolve. Evaluate the corrected image at the field edges and at the resolution your application requires.
Which Mechanical and Filter Option Should I Order?
Match the mechanical drawing to your lens holder, sensor position, and rear clearance. Choose the filter for your illumination spectrum and sensor stack. This page offers M12 mechanical versions; the product page lists the complete options. Contact engineering if you need help confirming the combination.
