Wide Angle Lens – M501814009324

M501814009324 is Wide angle 5-Megapixel lens with 120° diagonal FOV, F2.4 1/4″ M5.5X0.25-mount, 0.2m MOD, suitable for surveillance and imaging applications.

1.8mm 5MP M5.5 Wide Angle Fixed Focal Lens

This 1.8mm M5.5 wide angle lens is a compact fixed focal lens designed for 5MP imaging systems that require an exceptionally broad field of view in a small optical package. With a 120° diagonal FOV on a 1/4″ sensor, F2.4 fixed aperture, and a 0.2m minimum object distance, it is well suited to compact camera modules and embedded vision devices requiring close-range wide-area imaging.

1.8mm M5.5 Wide Angle Lens Applications

Core Application Scenes

This 1.8mm 5MP wide angle lens is designed for compact imaging systems where the camera needs to cover a large area from a relatively short installation distance. Its 120° diagonal field of view makes it particularly useful when increasing scene coverage is more important than maintaining a narrow perspective.

The 0.2m minimum object distance also makes this lens suitable for close-range embedded imaging, where the camera may be installed near the monitored area. Potential applications include compact smart devices, small-area monitoring modules, interactive equipment, robotic perception modules, and embedded cameras that need to observe a broad surrounding area without using a physically large optical assembly.

With a fixed F2.4 aperture and 5MP optical performance, the lens provides a straightforward configuration for camera modules where the optical parameters need to remain stable after installation. Its M5.5 × 0.25 mounting thread and 0.7mm B.F.L. are also suitable for integration into customized compact camera housings.

The lens is particularly valuable in applications where wide coverage, short installation distance, compact mechanical dimensions, and 5MP imaging need to be balanced within one optical system.

Designed for close-range wide-area imaging in compact embedded camera and vision systems.

Engineers selecting a wide angle lens should evaluate sensor format, focal length, field of view, and installation distance together. Towin’s Sensor Guide provides useful information about sensor and lens matching, while the Lens Selection Guide covers the main factors involved in selecting an appropriate industrial camera lens.

Frequently Asked Questions

Q: What type of lens is this 1.8mm M5.5 lens?
A: It is a wide angle fixed focal lens designed for 1/4″ sensors, with a 1.8mm focal length and 120° diagonal field of view.

Q: Is the 1.8mm lens a fisheye lens?
A: It is not classified as a fisheye lens in this product classification. Although its 120° diagonal FOV is very wide, its optical characteristics are better described as a wide angle fixed focal lens.

Q: What is the field of view of this lens?
A: On a 1/4″ sensor, the lens provides approximately 120° diagonal, 93° horizontal, and 74° vertical field of view.

Q: What resolution does this lens support?
A: The lens is specified for 5MP resolution and is designed for 1/4″ image format camera systems.

Q: What is the minimum object distance of this lens?
A: The specified M.O.D. is 0.2m, making it suitable for applications that require relatively close-range imaging.

Q: What does the 0.7mm B.F.L. specification mean?
A: B.F.L., or back focal length, is the distance from the rear optical reference point of the lens to the image plane. The 0.7mm specification is important when mechanically integrating the lens with a compact camera module.

Q: What mounting thread does the lens use?
A: The lens uses an M5.5 × 0.25 mounting thread, which is intended for compact camera and embedded optical assemblies.

Q: Can Towin customize this type of wide angle lens?
A: Customization can be evaluated according to requirements such as sensor format, focal length, field of view, mounting thread, mechanical dimensions, and application environment. For project-specific requirements, contact Towin through the Contact page.
