Frequently asked questions
What sensors are compatible with the CIL085 8mm M12 lens?
The CIL085 has an 8.9mm image circle, which accommodates the Sony IMX678's 8.86mm image diagonal. For the IMX226, the 9.33mm full 12MP format exceeds the specified image circle; its 8.61mm 4K format fits within it. Check the selected sensor mode, corner performance, and mechanical clearances before committing to a camera design.
How much distortion does the CIL085 have?
The CIL085 has -0.9% TV distortion, specified at an 8.8mm image circle. Whether correction is needed depends on your measurement tolerance and imaging geometry. For dimensional measurement, validate the calibrated system at your working distance.
What is the difference between the F/3.0 and F/4.4 CIL085 variants?
These are separate fixed-aperture versions. F/3.0 is specified for up to 12MP at 1.55μm pixel pitch, while F/4.4 is specified for 6MP–8MP. F/4.4 trades light throughput for more depth of field. Choose based on the detail you need, available illumination, and exposure time.
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.
