Description

The Arducam LN049 (model C20280M12) is a precision-engineered varifocal lens built for developers and integrators requiring adaptable imaging solutions. Its C-mount interface and 2/3″ optical format make it ideal for pairing with the Raspberry Pi HQ Camera’s 1/2.3″ IMX477 sensor via the included C-CS adapter, ensuring a secure mechanical and optical coupling.

Engineered for embedded vision systems, this lens provides exceptional optical clarity across its entire focal range. The wide F1.6 aperture maximizes light intake for applications in variable or dim lighting conditions, while the robust metal housing offers durability for industrial, surveillance, and scientific imaging environments where consistent performance is critical.

Key Features

  • Varifocal design allows adjustment from a wide 125° horizontal field of view at 2.8mm to a narrower 43° at 12mm.
  • Manual focus ring provides precise control for sharp imaging at distances as close as 0.3 meters.
  • Wide adjustable aperture (F1.6) optimizes exposure and depth of field for low-light and high-detail applications.
  • Compatible with Raspberry Pi HQ Camera and Arducam IMX477/577 camera boards via standard C-mount.
  • Includes a C-CS adapter for seamless mounting on CS-mount camera interfaces.
  • Durable all-metal body construction ensures long-term stability and resistance to wear.
  • Optical format supports 2/3" sensors, providing a large image circle for high-quality sensor coverage.

Applications

  • Machine vision and industrial inspection systems on Raspberry Pi platforms.
  • Surveillance and security camera systems requiring adjustable zoom and focus.
  • Scientific imaging and microscopy applications with embedded cameras.
  • Robotics and autonomous vehicle vision sensing.
  • High-quality video recording and photography projects with the Raspberry Pi HQ Camera.

Frequently Asked Questions

Is this Arducam lens compatible with the standard Raspberry Pi Camera Module V2?

No, this C20280M12 lens is designed for the Raspberry Pi HQ Camera (using the IMX477 sensor) and other cameras with a CS-mount or C-mount interface. The standard Camera Module V2 uses a smaller M12 mount and is not compatible without additional, non-standard adapters. For the HQ Camera, use the included C-CS adapter for proper mounting and flange distance alignment.

How do I adjust the focus and focal length on this varifocal lens?

This lens features two manual adjustment rings. The front ring controls the focal length (zoom), allowing you to select a field of view between 2.8mm and 12mm. The rear ring controls the focus. Rotate it until your subject appears sharp on the camera's live preview. For best results, set your desired zoom first, then fine-tune the focus. The lens has a minimum focusing distance of 0.3 meters.

What is the purpose of the included C-CS adapter, and when should I use it?

The C-CS adapter allows you to mount this C-mount lens onto a camera with a CS-mount thread, which is a smaller diameter. The Raspberry Pi HQ Camera module has a CS-mount interface. Therefore, you must attach the adapter to the lens first, then screw the combined unit onto the camera. This ensures the correct flange focal distance (17.53mm) is maintained for optimal image sharpness and focus range.

What is the maximum sensor size this lens can cover without vignetting?

The Arducam LN049 lens has an optical format of 2/3", meaning it projects an image circle large enough to fully cover sensors up to that size. The Raspberry Pi HQ Camera uses a 1/2.3" IMX477 sensor, which is significantly smaller. Therefore, the lens will cover the entire sensor area without any vignetting or dark corners, utilizing the central, sharpest portion of the optical field.
