Frequently asked questions

What sensors work with the CIL032 3.2mm CS-mount lens?

The CIL032 supports 1/1.7\" sensors up to 12MP including the Sony IMX226 and IMX178. The 9.3mm image circle covers these sensor formats fully.

How wide is the CIL032 field of view?

The CIL032 delivers 154° diagonal field of view on a 1/1.7\" sensor. Calculate your exact horizontal and vertical angles at https://commonlands.com/pages/camera-field-of-view-calculator.

Does the CIL032 work with the Raspberry Pi HQ camera?

Yes. The CIL032 is compatible with the Raspberry Pi High Quality camera via its CS-mount thread. No adapter required.

What is the distortion on the CIL032 CS lens?

The CIL032 has 12% TV distortion — expected for a 154° wide-angle CS lens. This is manageable with software correction for applications that require straight-line accuracy.

Does the CIL032 ship same day from the US?

Orders placed before 12 PM PST ship same day from Commonlands in San Diego, California. Contact us for current stock on specific CIL032 variants.

What are the CIL032 filter options?

The CIL032 is available with a 650nm IR cut filter (CIL032-F2.0-CSA650) for daylight use, or without filter (CIL032-F2.0-CSANIR) for NIR-sensitive applications. A third F/2.2 variant (CIL032-F2.2-CSANIR) is also available.

The CIL032 is a 3.2mm CS-mount lens with a 154° diagonal field of view on 1/1.7" sensors, resolving 12MP at F/2.0. The all-glass, all-aluminum construction weighs 54g — heavier than an M12 but built for CS-mount cameras that need a wide-angle option without adapters.

At 12% TV distortion, this is a wide-angle lens that trades geometric perfection for coverage. Good for surveillance, area monitoring, and robotics navigation where 154° of scene coverage matters more than straight lines at the edges. The 9.3mm designed image circle covers 1/1.7" sensors like the IMX226 and IMX178 with margin. Check your exact field angles at https://commonlands.com/pages/camera-field-of-view-calculator.

All-glass optics in an aluminum barrel. Two filter variants: order CIL032-F2.0-CSA650 with the 650nm IR cut filter for daylight-only applications, or CIL032-F2.0-CSANIR without filter for NIR-sensitive setups. A third variant, CIL032-F2.2-CSANIR, ships in CS-mount A configuration at F/2.2.

Mechanically compatible with e-con Systems (7–13mm tall mount), Allied Vision Alvium, FLIR Blackfly S, iDS uEye LE (Rev1.1 yes, Rev1.2 requires PN ending in "C-NO"), The Imaging Source M12, and D3 Engineering camera modules. Also compatible with the Raspberry Pi High Quality camera.

Ships same day from San Diego for orders placed before 12 PM PST. Drop-in CS-mount threading means you can swap this lens against other CS-mount options without reconfigurating your camera housing.
