Hikrobot MVL-MF1228M-8MP

Fixed-lens imaging geometry

A fixed 12 mm focal length and Ø11 mm (2/3") image circle define the imaging geometry of MVL-MF1228M-8MP. The C-mount lens provides a 48.57° diagonal, 37.88° horizontal, and 32.04° vertical field of view. Distortion is stated at 0.28%, while the manual iris spans F2.8 to F16, giving the integrator direct optical control over aperture for a fixed camera position.

The 0.1 m minimum object distance supports compact inspection layouts where the target sits close to the lens. Manual focus suits a station whose working geometry is set during commissioning, and manual iris adjustment allows the aperture to be fixed for that lighting arrangement. The Ø32 mm × 39.4 mm body and 75.1 g mass help with fixture planning; operation is specified from –10 °C to 50 °C.

MVL-MF1228M-8MP is the fixed-view choice beside MVL-MZ0645A-05. Select the 12 mm lens when its stated 37.88° horizontal and 32.04° vertical fields, Ø11 mm coverage, and 0.1 m close-focus limit define the station. Select MVL-MZ0645A-05 when a 1/2" format and an adjustable 0.6 x to 4.5 x magnification range are more important than a single focal length and explicitly stated angular view.

Specifications

Selection and applications

Fixed-field inspection with 12 mm optics. Close-range imaging from 0.1 m. Low-distortion imaging over an Ø11 mm circle.

Minimum kit: Combine MVL-MF1228M-8MP with an Ø11 mm (2/3") C-mount camera, the camera's data cable, and its specified power source.

Nearby in the range: MVL-MZ0645A-05 — Choose it when a 1/2" C-mount setup needs adjustable 0.6 x to 4.5 x magnification..

FAQ

What sensor image size can MVL-MF1228M-8MP cover through C-mount?

The lens is specified for an Ø11 mm image size, identified as 2/3", and uses C-mount with a 17.526 mm flange back length. These figures define the optical coverage and mechanical interface to check when matching the lens to a camera.

What field of view is stated for the fixed 12 mm focal length?

The listed field is 48.57° diagonal, 37.88° horizontal, and 32.04° vertical. These angles provide the starting geometry for a fixed inspection station; the actual object coverage also depends on the selected working distance.

How close can an object be placed to the MVL-MF1228M-8MP?

The minimum object distance is 0.1 m. This supports short lens-to-object layouts, while the final station still needs focus set manually and should use the stated fields of view to determine whether the target region fits the frame.

How are focus and aperture adjusted on this 12 mm lens?

Both focus and iris are manual. The iris range is F2.8 to F16, so aperture is set directly on the lens for the station's lighting and imaging requirements; focus is likewise established manually for the selected object distance.

Which filter thread and body envelope affect mechanical integration?

The filter thread is M30.5 × 0.5, and the body measures Ø32 mm × 39.4 mm with a mass of 75.1 g. Use these dimensions for filter, fixture, and clearance planning around a C-mount camera assembly.

What operating temperature range is listed for MVL-MF1228M-8MP?

The stated range is –10 °C to 50 °C. Keep the lens within this interval when defining the inspection environment, and account for its manual focus and iris settings if the station will operate across changing thermal conditions.
