Frequently asked questions

What sensors does the CIL436 zoom M12 lens support?

The CIL436 covers 1/2.7\" sensors at up to 2MP with 3μm pixel pitch, projecting a 6.7mm image circle.

How much zoom range does the CIL436 provide?

2.5-3X optical zoom from 4mm to 9mm EFL. At 4mm you get 141° FoV. The lens narrows to a normal field of view at the 9mm end.

Is the CIL436 compatible with FLIR Blackfly S cameras?

Yes. The CIL436 is mechanically compatible with FLIR Blackfly S board-level cameras, Allied Vision Alvium S-mount, The Imaging Source M12, and Basler Dart S-mount.

What is the distortion on the CIL436 at the wide end?

At 4mm (wide), distortion is -65%. This is high barrel distortion typical of wide-angle zoom designs. If your application needs geometric accuracy at the wide end, a fixed-focal low-distortion lens is a better choice.

Does the CIL436 come with an IR cut filter?

Both options are available. Order CIL436-F2.0-M12A650 with the 650nm IRC filter for visible-light-only applications, or CIL436-F2.0-M12ANIR without the filter for NIR or dual-band setups.

Does the CIL436 M12 zoom lens ship from the US?

Yes. Orders placed before 12 PM PST ship same day from our San Diego warehouse.

The CIL436 is a 4mm-9mm varifocal zoom M12 lens with approximately 2.5-3X optical zoom for up to 2MP on 1/2.7" sensors. This is a wide-angle zoom, covering 141° at the 4mm end across a 6.7mm image circle. If you need adjustable field of view without swapping lenses, the CIL436 covers the wide-to-normal range that most embedded vision projects land in.

The tradeoff for zoom flexibility is distortion. At the wide end, the CIL436 hits -65% barrel distortion, which rules out any application requiring geometric accuracy without heavy software correction. Surveillance, general monitoring, and prototype development where FoV tuning matters more than linearity are the right fit. At the telephoto end the distortion drops significantly. Use the field of view calculator at https://commonlands.com/pages/camera-field-of-view-calculator to model coverage on your specific sensor format.

Glass construction in an aluminum barrel at 30g. F/2.0 at the wide end, stopping down to F/3.0 at 9mm. Available with 650nm IR cut filter (CIL436-F2.0-M12A650) or without (CIL436-F2.0-M12ANIR). Focus is adjusted after securing the lens in its mount.

Broad mechanical compatibility: works with Allied Vision Alvium, FLIR Blackfly S, The Imaging Source, and Basler Dart S-mount cameras. Uses the Commonlands CLA019 lens holder with a 10-12mm tall mount. Check with iDS directly for uEye LE compatibility.

Ships same day from San Diego for orders before 12 PM PST. Contact Commonlands for volume pricing on production quantities.
