Wide Angle Lens – M802812009728F

M802812009728F is 48-Megapixel wide-angle CCTV lens with Built-In IR Filter, 1/2″ 2.8mm 120° M8.5×0.25 mount, F2.8 aperture, for security surveillance.

2.8mm M8.5 48MP Wide Angle Lens

This 2.8mm M8.5 48MP wide angle lens is designed for compact imaging systems that require high resolution and a broad field of view in a small optical package. With a 120° diagonal FOV, 97° horizontal FOV, and 74° vertical FOV, the lens captures a large scene area while maintaining a compact 6.21mm total optical length. Its 48MP resolution capability makes it suitable for high-detail imaging with modern high-resolution sensors.

Featuring a fixed 2.8mm focal length, F2.8 aperture, M8.5×0.25 mount, and 0.2m minimum object distance, this miniature lens provides a practical combination of wide coverage, compact mechanical integration, and high-resolution imaging. The fixed iris simplifies system integration, while the IRCF + 6P optical structure supports compact camera module applications where size and image detail are important.

2.8mm M8.5 48MP Wide Angle Lens Applications

Core Application Scenes

Compact Wide-View Camera Modules

The combination of a 2.8mm focal length and 120° diagonal FOV allows this lens to cover a large scene from a relatively compact camera position. It can be considered for miniature cameras used where a conventional longer focal-length lens would provide insufficient coverage.

The M8.5×0.25 mount and 6.21mm TTL are particularly relevant to compact optical assemblies where available installation space is limited. The 0.2m M.O.D. also provides flexibility for applications requiring imaging at relatively short distances.

High-Resolution Embedded Imaging

With a stated 48MP resolution, this lens is positioned for camera modules using high-pixel-count sensors. The wide field of view allows the system to retain broad scene coverage while taking advantage of a high-resolution image sensor.

This configuration can be considered for embedded vision devices, compact inspection cameras, smart imaging modules, and other systems where both optical coverage and image detail are important.

Compact Monitoring and Scene Capture

The 97° horizontal and 74° vertical FOV provide substantial horizontal and vertical scene coverage. This makes the lens suitable for compact camera systems that need to monitor a relatively wide area without using a physically large optical assembly.

The < -14% TV distortion should be taken into account during system design, especially when image geometry and straight-line reproduction are important.

Designed for compact high-resolution wide-angle imaging applications where small mechanical dimensions and broad scene coverage are required.

Frequently Asked Questions

Q: What is the focal length of this 48MP wide angle lens?
A: The lens has a fixed 2.8mm focal length, providing a wide viewing angle for compact camera systems.

Q: What field of view does the 2.8mm lens provide?
A: It provides a 120° diagonal FOV, 97° horizontal FOV, and 74° vertical FOV.

Q: Is this lens a fisheye lens?
A: No. Although the lens has a wide 120° diagonal FOV, the supplied specifications do not identify it as a fisheye optical design.

Q: Does this lens support 48MP resolution?
A: The specified resolution is 48MP, making the lens suitable for camera systems designed around high-resolution image sensors.

Q: Is this a low distortion lens?
A: No. Its specified TV distortion is below -14%, so it should not be positioned as a low-distortion lens.

Q: What mount does this miniature lens use?
A: It uses an M8.5×0.25 threaded mount, making it suitable for compact camera module integration.

Q: What is the minimum object distance of this lens?
A: The specified M.O.D. is 0.2m, or approximately 200mm.

Q: What does IRCF + 6P mean in the optical structure?
A: IRCF indicates an infrared cut filter, while 6P refers to a six-plastic-element optical construction. IRCF should not be interpreted as an IR-corrected optical design.
