Frequently asked questions
What sensors are compatible with the CIL085 8mm M12 lens?
The CIL085 covers 1/1.7″ and 1/1.8″ sensors including the Sony IMX226, Sony IMX678, and ON Semiconductor AR0820. Its 8.9mm image circle fully covers those formats.
How much distortion does the CIL085 have?
The CIL085 has -0.9% TV distortion at the 8.8mm image circle. That is low enough for barcode scanning, OCR, and dimensional measurement in most pipelines without software correction.
What is the difference between the F/3.0 and F/4.4 CIL085 variants?
The F/3.0 variant resolves 12MP at 1.55μm pixel pitch, so you pick it when detail matters most. The F/4.4 variant resolves 6-8MP and gives you more depth of field when object distance varies.
Which lens holders work with the CIL085 M12 lens?
The Commonlands CLA019 is one compatible holder, and other mounts work as well. FLIR Blackfly S, Allied Vision Alvium, Basler Dart, The Imaging Source, and iDS uEye LE Rev1.1 are mechanically compatible, while e-con Systems boards need an 8-15mm tall mount.
Does the CIL085 ship same day from the US?
Yes. In-stock CIL085 lenses ship same day from San Diego for orders placed before 12 PM PST.
Can I get a mechanical drawing or STP file for the CIL085?
Yes. The product page includes a 3D model viewer, and engineering@commonlands.com can provide .STP files and detailed mechanical drawings for CAD integration.
