Low Distortion Lens – M804512706630F

M804512706630F is Low distortion CCTV lens with Built-In IR Filter, F3.0 aperture, 73° 1/2.7″ M8x0.35 mount, for reliable security surveillance applications.

4.5mm M8 Low Distortion Lens

The 4.5mm M8 low distortion Wide Angle Low Distortion Lens is a compact fixed focal lens designed for embedded camera modules, smart monitoring devices, robotic vision systems, and other space-constrained imaging applications. With a 73° diagonal FOV, F3.0 aperture, <1% TV distortion, and 8.48mm TTL, this M8 lens provides a practical balance between wide scene coverage, image geometry, and compact mechanical integration.

Its M8x0.35 mount, 0.2m minimum object distance, and 4G+IRCF optical structure make it suitable for compact vision systems where installation space and image consistency are important.

M8 Low Distortion Lens Highlights

• 73° Wide-Angle FOV — Provides broad scene coverage on a 1/2.7″ sensor.
• Low-Distortion Imaging — TV distortion is specified at <-1% for more consistent image geometry.
• 4.5mm Fixed Focal Length — Provides stable imaging characteristics without mechanical focal adjustment.
• Compact M8x0.35 Mount — Suitable for small embedded camera modules and space-limited devices.
• 8.48mm TTL — Short optical length supports compact camera integration and mechanical packaging.

4.5mm M8 Low Distortion Lens Applications

Core Application Scenes

The compact dimensions and moderate wide-angle coverage make this lens suitable for applications where the camera needs to capture a relatively broad scene without using an extreme fisheye design.

Typical applications include:

• Compact embedded vision cameras
• Smart monitoring modules
• Indoor visual monitoring
• Robotic observation cameras
• IoT imaging devices
• Short-range visual sensing
• Compact inspection and detection systems
• Small form-factor camera modules

For applications requiring controlled image geometry, the < -1% TV distortion specification helps maintain more predictable object positioning across the image. The 0.2m M.O.D. also allows the lens to be used for relatively close-range scenes.

Designed for compact embedded camera applications where wide scene coverage, short optical length, and controlled distortion are required.

Compatible Device Types

This 4.5mm M8 lens can be considered for integration with:

• 1/2.7″ 2MP camera modules
• Compact embedded cameras
• Smart monitoring cameras
• Robotic vision modules
• IoT visual sensing devices
• Miniature inspection cameras

For sensor and image-format matching, see the Sensor Guide and Lens Selection Guide. You can also use the FOV Calculator to estimate the relationship between sensor size, focal length, and field of view.

Optical Design Considerations

The 4.5mm focal length provides a 73° diagonal, 66° horizontal, and 39° vertical FOV on a 1/2.7″ sensor. This makes the lens a practical Wide Angle Lens rather than an extreme-angle fisheye design.

The fixed F3.0 aperture provides a straightforward optical configuration for compact camera systems, while the 4G+IRCF structure incorporates an infrared cut filter for standard visible-light imaging.

Frequently Asked Questions

Q: What type of lens is the 4.5mm M8 lens?
A: It is a fixed focal, wide-angle M8 miniature lens designed for compact camera modules and embedded imaging systems.

Q: What sensor size is this M8 lens designed for?
A: The specified FOV is based on a 1/2.7″ image format, with a 73° diagonal, 66° horizontal, and 39° vertical field of view.

Q: Is this 4.5mm M8 lens a fisheye lens?
A: No. The 73° diagonal FOV represents a moderate wide-angle configuration rather than an extreme fisheye design.

Q: What is the distortion specification?
A: The specified TV distortion is <-1%. This helps provide more controlled image geometry for applications where excessive bending of straight lines should be limited.

Q: What does IRCF mean in this lens specification?
A: IRCF refers to an IR Cut Filter. It is used for standard visible-light imaging and should not be confused with an IR Corrected optical design.

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

Q: What is the total track length of the lens?
A: The T.T.L. is 8.48mm, supporting integration into compact camera modules where optical packaging space is limited.

Q: Can this lens be customized for a different camera system?
A: For OEM or application-specific requirements involving focal length, FOV, sensor format, distortion, mounting, or mechanical dimensions, contact TOWIN through the Contact page to discuss the optical requirements.
