Wide Angle Lens – M803312711520F

M803312711520F is Ultra wide angle 3-Megapixel CCTV lens with Built-In IR Filter, Max Φ7.2mm format, M8X0.35 mount, and F2.0 aperture for security surveillance.

3.3mm M8 Wide Angle Lens

This 3.3mm M8 wide angle lens is designed for 1/2.7″ image sensors and delivers an ultra-wide 142° diagonal field of view with 3MP resolution. Its F2.0 aperture, compact 15.71mm TTL and M8x0.35 mount make it suitable for miniature camera modules that require extremely broad scene coverage from a small optical package.

The lens uses a 3.3mm fixed focal length, manual focus and a 6G+IRCF optical structure. With <-30% TV distortion, it is intended for applications where maximum viewing coverage is more important than rectilinear image geometry.

Product Highlights at a Glance

• 142° diagonal FOV for extremely wide scene coverage on 1/2.7″ sensors.
• 3MP resolution suitable for compact imaging and monitoring modules.
• 3.3mm fixed focal length provides a wide perspective from a miniature optical assembly.
• M8x0.35 mount supports compact camera designs where installation space is limited.
• F2.0 aperture with 6G+IRCF structure combines a relatively bright optical system with IR-cut filtering.

3.3mm M8 Wide Angle Lens Applications

Core Application Scenes

• Designed for wide-area monitoring applications where a single compact camera needs to capture a broad surrounding scene.
• Miniature surveillance cameras requiring very wide coverage from a small M8 optical interface.
• Embedded vision systems where the available installation space is restricted but a large viewing angle is required.
• Robotic observation and mobile imaging where a broad perspective can help monitor the surrounding environment.
• IoT and smart-device cameras that require compact optics with wide scene coverage.
• Equipment monitoring where the camera must observe a relatively large area from a short installation distance.

Because this lens provides a 142° diagonal FOV and <-30% TV distortion, the optical design intentionally prioritizes coverage over low-distortion imaging. For applications requiring geometrically accurate machine-vision measurement, a Low Distortion Lens would be more appropriate.

For systems where ultra-wide viewing coverage is the primary requirement, this lens can be evaluated together with TOWIN’s Wide Angle Lenses range.

Compatible Devices

• 1/2.7″ 3MP camera modules
• Compact surveillance camera modules
• Miniature embedded cameras
• Smart monitoring devices
• Robotics observation cameras
• IoT imaging devices
• Space-constrained camera assemblies

When selecting a lens for a camera module, sensor format, field of view, image circle and mounting dimensions should be considered together. TOWIN’s Lens Selection Guide provides additional guidance for matching lens specifications to camera requirements.

You can also use the FOV Calculator to estimate the relationship between focal length, sensor size and viewing coverage during system design.

Frequently Asked Questions

Q: What type of lens is this 3.3mm M8 lens?
A: It is a fixed focal length M8 lens with an ultra-wide 142° diagonal field of view. Based on its very wide FOV and <-30% TV distortion, it is classified as a fisheye lens as well as a wide angle lens.

Q: What sensor size is this lens designed for?
A: The specified field of view is based on a 1/2.7″ image sensor. The maximum image format is Φ7.2mm.

Q: What is the field of view of the 3.3mm lens?
A: On a 1/2.7″ sensor, the lens provides 142° diagonal, 115° horizontal and 60° vertical field of view.

Q: Is this a low distortion lens?
A: No. The specified TV distortion is <-30%, so this lens is designed for extremely wide coverage rather than low geometric distortion. It should not be categorized as a Low Distortion Lens.

Q: Is the M8 lens IR corrected?
A: The lens has a 6G+IRCF structure. IRCF refers to an IR cut filter structure and does not by itself indicate an IR-corrected optical design.

Q: What applications are suitable for this lens?
A: It is suitable for compact surveillance, embedded cameras, IoT imaging, robotics observation and equipment monitoring applications where very wide scene coverage is more important than low distortion.

Q: Can this lens be used for machine vision measurement?
A: It may be used for certain observation-oriented vision systems, but the <-30% distortion makes it unsuitable for applications that require highly accurate geometric measurement without image correction. For those applications, a low-distortion machine vision lens should be considered.

Q: Can TOWIN customize this type of M8 lens?
A: TOWIN develops compact industrial and miniature optical systems for different sensor formats, focal lengths, fields of view and mechanical requirements. For a customized requirement, contact the TOWIN optical engineering team.
