Narrow-angle C-mount observation
A 75 mm focal length gives MA7520M-5MP a narrow view on its 11 mm, 2/3-inch image format: 8.4° diagonal, 6.7° horizontal and 5.0° vertical. The C-mount optic opens to F2.0 and stops down to F22, with manual iris and focus. Distortion is listed at 0.02%, supporting feature location and inspection where geometric consistency matters.
The narrow view angles suit distant component checks, alignment targets and small regions viewed from a stand-off position. Minimum object distance is 0.9 m, so this is not the close-focus choice among the C-mount lenses. Its 45 mm diameter, 71.7 mm length and 223 g mass form a compact mechanical envelope, while the M40.5 × 0.5 front thread identifies the filter interface.
MVL-MF2528M-10MPE has the same C-mount flange distance of 17.526 mm but uses 25 mm focal length, a 22.81° diagonal view and a 0.15 m minimum distance. MVL-MF1228M-10MPE widens further to 47.66° at 12 mm and focuses from 0.1 m. Select MA7520M-5MP when the application needs the 75 mm focal length and 5.0° vertical view rather than close or wide imaging.

Selection and applications
Narrow-angle distant inspection. Alignment-target observation. Low-distortion feature location.
Minimum kit: Fit the lens to a C-mount camera with a 17.526 mm flange back length and set manual focus and the F2.0 to F22 iris beyond the 0.9 m minimum distance.
Nearby in the range: MVL-MF2528M-10MPE — Prefer it for a 25 mm focal length, 22.81° diagonal view and 0.15 m minimum distance.; MVL-MF1228M-10MPE — Prefer it for a 12 mm focal length, 47.66° diagonal view and 0.1 m minimum distance..

FAQ
What view angles result from the 75 mm focal length?
The listed angles are 8.4° diagonally, 6.7° horizontally and 5.0° vertically on the 11 mm, 2/3-inch image format. These narrow angles make the lens a candidate for a small inspection region viewed from a greater distance.
How close can an object be placed in front of MA7520M-5MP?
Minimum object distance is 0.9 m. The camera position must therefore leave at least that object clearance, after which manual focus is set for the actual station geometry and checked across the intended temperature range.
Which camera and filter threads are used by this lens?
The camera connection is C-mount with a 17.526 mm flange back length. At the front, the filter thread is M40.5 × 0.5; the two interfaces serve different sides of the optic and should be treated separately in the mechanical design.
What adjustment range does the manual iris provide?
The manual aperture spans F2.0 to F22, and focus is manual as well. The wide stop range supports adjustment of illumination and imaging geometry during setup, with both rings then held at the commissioned settings.
How does this lens differ from the 25 mm C-mount options?
Its 75 mm focal length produces a 5.0° vertical view and requires a 0.9 m minimum distance. MVL-MF2528M-10MPE uses 25 mm, gives a 14.14° vertical view on 11.2 mm format and focuses from 0.15 m.
