Maximum scene coverage in a short C-mount lens
A 94° diagonal view makes HF0420M the broadest-angle lens in this group. Its 4 mm focal length covers a 9 mm, 1/1.8-inch image format with 82.9° horizontal and 66.5° vertical angles. The C-mount optic opens at F2.0, lists 0.5% optical distortion and focuses from a 0.1 m minimum object distance, concentrating on close, wide-area observation.
The coverage suits part-presence checks, tray overview and assembly monitoring when camera stand-off is restricted. A 38.2 mm diameter, 34.87 mm length and 61.5 g mass keep the camera head compact. The 17.526 mm flange back length establishes C-mount geometry, while the -10 to 50 °C range sets the operating boundary for the installed optical system.
MVL-MF0824M-5MPE uses an 8 mm focal length and an 11 mm image circle, reducing the diagonal view to 70.6° while keeping a 0.1 m minimum distance. MVL-MF1228M-10MPE narrows further to 47.66° at 12 mm and covers 11.2 mm. Choose HF0420M when the 94° overview and smaller 9 mm format matter more than the tighter framing of the longer lenses.

Selection and applications
Close tray overview. Wide assembly monitoring. Part-presence capture in confined space.
Minimum kit: Install HF0420M on a C-mount camera with a 17.526 mm flange back length and focus the F2.0 optic at or beyond its 0.1 m minimum object distance.
Nearby in the range: MVL-MF0824M-5MPE — Prefer it for an 8 mm focal length, 70.6° diagonal view and 11 mm image circle.; MVL-MF1228M-10MPE — Prefer it for a 12 mm focal length, 47.66° diagonal view and manual F2.8 to F16 iris..

FAQ
What angular coverage is provided by the 4 mm lens?
HF0420M provides a 94° diagonal view, 82.9° horizontal view and 66.5° vertical view on a 9 mm, 1/1.8-inch image format. These are the widest listed angles among the compared C-mount lenses.
How close may the object be placed for wide-area observation?
The minimum object distance is 0.1 m. That short limit and 4 mm focal length support close overview imaging, with focus set for the actual inspection plane after the C-mount camera is installed.
What aperture and distortion values characterize HF0420M?
The lens opens at F2.0 and its optical distortion is listed at 0.5%. Those values should be included when selecting illumination and establishing geometric calibration for the full 94° diagonal scene.
Which body dimensions matter in a restricted camera envelope?
The lens measures 38.2 mm in diameter by 34.87 mm long and weighs 61.5 g. It uses a C-mount with a 17.526 mm flange back length, defining both its outer clearance and camera-side geometry.
How does the 8 mm MF lens reduce the captured scene?
MVL-MF0824M-5MPE changes focal length from 4 mm to 8 mm and diagonal coverage from 94° to 70.6°. It also covers a larger 11 mm image circle and retains the same 0.1 m minimum object distance.
