12mm C Mount lens for up to 2/3"

The CIL592 is a 12mm C-mount lens for 2/3" sensors up to 5MP. The F/1.4 aperture gives more light than a typical compact inspection lens, which helps when exposure time is limited or the camera needs to keep gain under control. It delivers a 39° × 33° field of view on the Sony IMX264 and the Sony IMX250.

This is a C-mount lens, not an M12/S-mount lens. Check the camera for a 1"-32 C-mount thread and the normal 17.526mm C-mount flange distance before selecting it. That mount geometry is part of the optical system, so adapter thickness and sensor position matter.

The listed part number is CIL592-F1.4-CMANIR, described as F/1.4, without filter, C-Mount A. The current product page says Commonlands tries to restock quickly and asks customers to contact for availability. Do not assume same-day shipment unless the page shows in-stock inventory when you order.

Use this lens when you need a 12mm focal length on a 2/3" 5MP C-mount camera and want the light throughput of F/1.4. If the application is dimensional measurement, verify distortion, working distance, and focus range against the drawing or a test image before releasing the camera design.
