IMX490やOS08A10など、2/3インチまでの4.5mm M12レンズ

The CIL344 is a 4.5mm wide-angle M12 lens that covers sensors up to 2/3" format, including the IMX490 and OS08A10. The F/2.7 variant resolves 12MP across a 9.3mm image circle, so it makes sense when pixel count matters. The F/1.9 variant resolves 3MP with an 11.1mm image circle, which is the better trade if light gathering matters more than fine detail.

The lens gives 125° at the 11.0mm image circle, and distortion is -3% F-Θ at that same field height. That is moderate for this much coverage, so you can get a very wide scene without stepping all the way into fisheye behavior. The choice between F/2.7 and F/1.9 is straightforward. Use F/2.7 at 2.2μm pixel pitch for high-resolution inspection, and use F/1.9 at 4.2μm pixel pitch when low-light robotics or drone payloads need more light. Calculate your field of view to match the lens to your sensor.

The optics use all-glass elements in an aluminum barrel, and the first surface has BBAR coating. The standard M12A version handles general integration, while the M12B IP69K variant is the better choice for washdown, outdoor, and dusty environments where you do not want to add sealing work later.

The lens mounts directly to FLIR Blackfly S, Allied Vision Alvium, iDS uEye LE, The Imaging Source, and Basler Dart board cameras. It is compatible with the Commonlands CLA024 lens holder (22mm spacing), among other mounting options. e-con Systems boards need a 12–15mm tall holder.

Commonlands keeps this lens in stock in San Diego and ships same day for orders placed before 12 PM PST. An optional 660nm IR cut filter is available. Contact our optical engineers for volume pricing or depth of field estimates with the calculator
