16mm M12 Lens for sensors up to 1/2" such as OX05B1S

The CIL161 is an IR corrected 16mm M12 lens for 1/2" sensors, resolving 3–5MP at 2.2μm pixel pitch. At 15.6mm EFL with F/2.0, this is a telephoto M12 optic that gives you a tight 28.8° field of view across the 8.0mm image circle — ideal for license plate recognition, perimeter surveillance, and long-range inspection where you need to resolve detail at distance.

The -0.3% rectilinear distortion is essentially zero. Straight lines stay straight. That matters for dimensional measurement, OCR at range, and any application where geometric accuracy drives your result. The IR correction keeps the focal plane stable across visible and near-IR wavelengths, so day/night cameras using RGBIR sensors like the OX05B1S stay sharp without mechanical refocus.

All-glass construction in a compact 5g package. The glass optics and aluminum barrel handle thermal expansion better than hybrid plastic-glass designs, which is why this lens works well in outdoor enclosures that cycle between direct sun and overnight cold.

Two filter options: CIL161-F2.0-M12A650 with 650nm IRC for standard daylight, CIL161-F2.0-M12ANIR without filter for NIR-sensitive setups. Compatible with FLIR Blackfly S, Allied Vision Alvium, iDS uEye LE, The Imaging Source, and Basler Dart cameras. e-con boards need a 10–13mm tall holder. The Commonlands CLA018 is the recommended M12 lens mount.
