Frequently asked questions
What sensors does the CIL552 12mm C-mount lens support?
The CIL552 fits 1.2″ sensors up to 25MP at 2.74µm pixel pitch, including the Sony IMX541. The 19.4mm image circle fully covers the 1.2″ sensor format.
What is the aperture range of the CIL552?
The aperture adjusts from F/2.8 to F/16. You can stop down for more depth of field in inspection setups, or you can run wide open at F/2.8 when light is tight. You can use depth of field calculator to estimate depth of field at your working distance.
How much distortion does the CIL552 produce?
Distortion is -0.22% from rectilinear. That is very low for a 12mm focal length covering a 19.4mm image circle, so the lens works for dimensional measurement without software correction in many systems.
Does the CIL552 have front filter threads?
No, the CIL552 does not have front filter threads. You should use sensor-side filtration or structured lighting if you need bandpass filtering.
Does the CIL552 ship same day from the United States?
Yes, Commonlands ships in-stock lenses same day from San Diego, California for orders placed before 12 PM PST.
Are 3D models available for the CIL552?
Yes, an interactive 3D viewer is available on the product page. You can contact engineering@commonlands.com if you need STP files or mechanical drawings for CAD integration.
