12mm C-Mount lens for up to 2/3" sensors such as IMX487 and Sony IMX536

The CIL532 is a 12mm C-mount lens for 2/3" sensors resolving up to 12MP at 2.2um pixel pitch. It matches sensors like the Sony IMX487 and IMX536, and the iris adjusts from F/2.0 to F/16. This lens sits in the useful center of the lineup because it gives you natural perspective without forcing a long working distance.

The CIL532 holds distortion to +0.05% across the 11.1mm image circle. That is essentially zero in this class, which is why the lens belongs in gauging, dimensional measurement, and any setup where straight edges matter. The 49° field of view gives you coverage that still looks natural on a 2/3" sensor. You can check the field on your sensor at field of view calculator

The lens uses an all-glass construction in a compact 61g barrel. The front takes M27x0.5 filters, and focus runs from 0.15m to infinity. The optical design is optimized for finite conjugate work, so it stays controlled at short distances where many general-purpose C-mount lenses start to soften or curve the field.

The standard C-mount thread and 17.526mm flange distance let the lens mount directly to cameras from Basler, FLIR, Lucid Vision, Allied Vision, and other industrial camera makers. The 12mm focal length remains one of the safest choices in machine vision because it balances field coverage and working distance without much drama.

The CIL532 is available as CIL532-F2.0-CMANIR without a filter. All in-stock units ship the same day from San Diego when you order before 12 PM PST. Volume pricing and Trioptics MTF data are available from our engineering team. You can estimate depth of field at depth of field calculator
