Wide Angle Lens – M802313013022F

M802313013022F is Wide-angle CCTV 3-Megapixel lens with Built-In IR Filter, 1/3″ & 1/2.9″ M8X0.5 mount lens F2.2 aperture, for security surveillance.

2.3mm M8 3MP 170° Wide Angle Lens

This 2.3mm M8 wide angle lens is designed for compact camera modules that require exceptionally broad scene coverage from a small optical assembly. It supports both 1/3″ and 1/2.9″ image formats, providing up to 170° diagonal FOV on a 1/2.9″ sensor and 160° diagonal FOV on a 1/3″ sensor.

The lens combines 3MP resolution, F2.2 aperture, and an M8×0.5 miniature mount for compact embedded camera applications. Its fixed iris, manual focus, and fixed zoom configuration provide a straightforward optical setup for camera module integration, while the 0.3m M.O.D. supports relatively close-range wide-area imaging.

With a 4.7mm BFL and 6G + IRCF construction, this lens is designed for applications where maximizing the captured scene is more important than maintaining low geometric distortion. Its extremely wide viewing angle makes it suitable for monitoring, embedded sensing, and compact observation systems.

2.3mm M8 170° Wide Angle Lens Applications

Core Application Scenes

The main strength of this lens is its ability to capture an extremely large viewing area from a compact M8 camera module. On a 1/2.9″ sensor, the lens reaches 170° diagonal and 143° horizontal FOV, making it suitable for systems where minimizing blind areas is more important than geometric accuracy.

The lens also supports a 1/3″ sensor, where it provides 160° diagonal and 130° horizontal FOV. This dual-format capability gives camera designers flexibility when selecting the image sensor for a compact imaging platform.

The 0.3m minimum object distance makes the lens suitable for relatively close-range scene observation, while the F2.2 aperture provides practical light-gathering performance for embedded camera systems.

Because the TV distortion is below -25%, this lens is intended for wide-area imaging rather than precision measurement. It is therefore best suited to monitoring, observation, sensing, and other applications where maximum field coverage is the primary optical requirement.

Designed for compact ultra-wide-angle imaging applications requiring extensive scene coverage and reduced blind spots.

Frequently Asked Questions

Q: What is the maximum field of view of this 2.3mm M8 lens?
A: On a 1/2.9″ sensor, the lens provides 170° diagonal FOV, 143° horizontal FOV, and 78° vertical FOV.

Q: What is the FOV on a 1/3″ sensor?
A: On a 1/3″ sensor, the lens provides 160° diagonal FOV, 130° horizontal FOV, and 90° vertical FOV.

Q: What sensor formats are supported?
A: The lens is specified for both 1/3″ and 1/2.9″ image formats.

Q: Is this a low distortion lens?
A: No. The TV distortion is below -25%, so this lens is designed primarily for extremely wide scene coverage rather than low-distortion imaging.

Q: Is the 2.3mm M8 lens a fisheye lens?
A: Although it provides an extremely wide FOV of up to 170°, the supplied product classification is Wide Angle Lens. It should not be automatically categorized as a fisheye lens based only on its field of view.

Q: What is the mount size?
A: The lens uses an M8×0.5 mount, making it suitable for miniature and compact camera modules.

Q: Can the focus be adjusted?
A: Yes. The lens uses manual focus. Its zoom is fixed and the focal length remains 2.3mm.

Q: What applications are suitable for this lens?
A: It is suitable for wide-area monitoring, compact embedded cameras, IoT imaging, robotic sensing, environmental observation, and other applications where broad scene coverage is more important than low distortion.
