19mm M12 Lens IP69K rated | 19mm S-Mount Lens for up to 1.3MP like AR0234

The CIL190 is a 19mm M12 telephoto lens with IP69K sealing for 1/2.6" sensors up to 1.3MP with 3μm–3.75μm pixel pitch. It gives you a 20° field of view at the 6.7mm image circle, so the lens stays tight enough for forward-looking automotive cameras that need reach instead of coverage. At F/1.6, it also keeps exposure times usable in low light, which matters when the vehicle moves from daylight into tunnels or dusk conditions.

Distortion is -0.7% TV, so straight lines stay controlled enough for lane detection and other forward-facing ADAS tasks. The 6.7mm designed image circle covers 1/2.6" sensors, and the 8.1mm maximum circle gives you a little more room if the format runs larger. The 4G all-glass design in an AL6061 barrel also helps limit focus shift through thermal cycling.

The IP69K rating means the lens survives high-pressure washdown, steam cleaning, and full submersion testing. That is the spec you want when the camera sits outside the vehicle instead of behind clean indoor glass. The BBAR coating on the first surface reduces flare from headlights and direct sun, which can otherwise erase contrast in automotive scenes.

The lens mounts on e-con Systems, Allied Vision Alvium, FLIR Blackfly S, and iDS uEye LE boards with the Commonlands CLA018 lens holder. You can calculate your depth of field to check your working distance range before you commit.
