Wide-Angle 3mm M12 Lens for up to 1/2.3" such as IMX477 and IMX577.

The CIL391 is a 3.25mm wide-angle M12 lens that delivers 154° field of view on 1/2.3" sensors like the IMX477 and IMX577. At F/2.8, 12MP resolution, and 5g total weight, this is the lens you want when replacing a GoPro-style camera module or building a compact wide-angle system from scratch.

The -16% TV barrel distortion is typical for a lens this wide — it is noticeable but correctable in software. The 7.9mm image circle covers 1/2.3" sensors fully, and the 13.9° chief ray angle is well-matched to modern BSI CMOS sensors. If you need sub-1% distortion, look at our rectilinear M12 lenses instead. The CIL391 trades geometric perfection for maximum angular coverage.

All-glass construction with an IP67-sealed M12A barrel and BBAR coating on the first surface. Three variants: CIL391-F2.2-M12ABR650 with blue-glass reflective 650nm IRC, CIL391-F2.8-M12A660 with standard 660nm IRC, and CIL391-F2.8-M12ANIR without a filter for NIR work. The 1.55μm pixel pitch rating means this lens resolves well on demanding small-pixel sensors.

Compatible with the Commonlands CLA024 lens holder. Also works with e-con Systems (12–15mm mount), D3 Engineering, iDS XLS, Allied Vision, Basler Dart, The Imaging Source M12, and Raspberry Pi HQ Camera boards.
