Low Distortion M8 Lens \| For up to 3MP sensors with 3μm pixels such as the AR0230

The CIL829 is a 2.8mm low distortion lens available in both M8x0.35 and M12x0.5 mount sizes for 1/2.8" sensors up to 3MP at 3μm pixel pitch. It gives you a 100° field of view across a 6.6mm image circle without the usual fisheye look. The M8 version weighs just 1.4g, so it fits weight-sensitive platforms where a normal M12 assembly feels oversized.

The key number is -1% distortion from rectilinear. That is very low for a 100° field. Most wide-angle lenses at this focal length run much higher barrel distortion, so the CIL829 saves you from building a software cleanup step into barcode reading, obstacle detection, and visual odometry.

The optical stack uses 1G6P construction in an aluminum barrel with a fixed F/2.55 aperture. The chief ray angle is 21°, so you should compare it with your sensor's microlens CRA specification before you commit. That check matters because edge shading shows up fast when the CRA mismatch is wrong. You can calculate your field of view

Five SKU variants cover M08A or M12A mount, with or without a 650nm IRC filter, plus an 850nm bandpass option for NIR applications. The M8 thread pitch is 0.35mm, which gives you finer focus adjustment than standard M12 hardware.
