21.6mm M12 Lens (IR-Cut Filter)
€73.81
21.6 mm low-distortion M12 lens for up to 1/1.8" sensors. On 1/1.8" sensors, the lens provides a 23.4° diagonal angle of view, making it suitable for applications that need a narrow field of view and tighter subject framing in a compact camera system. Optical distortion of 1.15% or less also makes it a practical option where straighter lines and more natural image geometry are preferred. Suitable for embedded vision, robotics, machine vision, and other systems that require longer focal length optics in M12 format.

Accessories
Aluminium adapter for using low-profile or short back focus M12 lenses with CS-mount cameras. It provides an M12 lens interface on a CS-mount camera body, making it useful when compact board lenses need to be fitted to CS-mount systems. Long focal length M12 lenses can also be used with a 5mm spacer ring when additional spacing is needed. This adapter is intended for short back focus lenses, and with some lens and camera combinations the filter may need to be removed to achieve proper fit or focus. The kit includes 2x M2 DIN914 set screws and a 0.9mm hex key. Selected configuration preview and CAD models Gallery photos show real products and may represent similar configurations.
