Frequently asked questions

What sensors does the CIL592 12mm C-mount lens support?

The CIL592 is listed for 2/3 inch sensors up to 5MP. The focal length is 12mm and the aperture is F/1.4.

What part number is listed for the CIL592?

The page lists CIL592-F1.4-CMANIR, described as F/1.4, without filter, C-Mount A.

Is the CIL592 an M12 lens?

No. The CIL592 is a C-mount lens. Use it with cameras that support a 1 inch-32 C-mount thread and the normal 17.526mm C-mount flange distance.

Does the CIL592 include an IR cut filter?

No. The listed part number is the ANIR version, which means without filter.

Is the CIL592 in stock?

The current page says Commonlands tries to restock quickly and asks customers to contact for availability. Check the live page or contact Commonlands before planning a build around immediate stock.

When should I choose the CIL592?

Choose the CIL592 when you need a 12mm focal length, 2/3 inch 5MP coverage, and an F/1.4 aperture on a C-mount camera.

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.

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.
