Low Distortion Lens – M801912811420F

M801912811420F is Low distortion Wide-angle 8-Megapixel CCTV lens with Built-In IR Filter, M8X0.35 mount, F2.0 aperture Suitable for security Surveillance.

1.9mm M8 8MP Low Distortion Wide Angle Lens

This 1.9mm M8 low distortion wide angle lens is designed for compact camera modules that require both broad scene coverage and controlled image distortion. Supporting 1/3.2″ and 1/2.8″ image formats, the lens delivers up to 123° diagonal FOV on the IMX415 sensor and 114° diagonal FOV on the AR1335, while maintaining TV distortion below -2.4%.

With an 8MP resolution, F2.0 aperture, and M8×0.35 mount, the lens combines high-resolution imaging with a compact mechanical package. Its 14.97mm TTL and 1G5P optical structure with IRCF make it suitable for miniature camera assemblies where optical performance and limited installation space need to be balanced.

The controlled distortion is particularly valuable for wide-angle imaging systems that need a broad field of view without the strong geometric deformation associated with ultra-wide or fisheye optics. This makes the 1.9mm M8 8MP lens a practical option for compact machine vision, embedded imaging, smart monitoring, and other high-resolution camera applications.

1.9mm M8 Low Distortion Lens Applications

Core Application Scenes

The key advantage of this lens is its combination of wide field of view and relatively low distortion. Unlike an ultra-wide lens designed primarily to maximize viewing angle, the <-2.4% TV distortion specification makes this model more suitable when straight-line reproduction and image geometry still matter.

The lens supports both 1/3.2″ and 1/2.8″ formats, with different FOV performance depending on the sensor. On the IMX415, it reaches 123° diagonal and 113° horizontal FOV, providing broad scene coverage for compact camera systems. On the AR1335, it provides 114° diagonal and 99° horizontal FOV.

The M8×0.35 mount allows integration into compact camera assemblies, while the F2.0 aperture supports practical imaging in indoor and controlled-light environments.

Designed for compact wide-angle imaging applications that require high resolution, broad coverage, and better geometric control than conventional ultra-wide optics.

Frequently Asked Questions

Q: What sensor formats are supported by this 1.9mm M8 lens?
A: The lens is specified for both 1/3.2″ and 1/2.8″ image formats, with different FOV performance depending on the sensor.

Q: What is the FOV on the IMX415 sensor?
A: On the IMX415, the lens provides 123° diagonal FOV, 113° horizontal FOV, and 78° vertical FOV.

Q: What is the FOV on the AR1335 sensor?
A: On the AR1335, the lens provides 114° diagonal FOV, 99° horizontal FOV, and 82° vertical FOV.

Q: Is this a low distortion lens?
A: Yes. The specified TV distortion is below -2.4%, giving the lens controlled distortion performance for a wide-angle design. The exact distortion behavior should still be evaluated against the requirements of the final imaging system.

Q: Is the 1.9mm M8 lens a fisheye lens?
A: No. Although the lens provides a wide FOV of up to 123° diagonal, its relatively low distortion makes it more appropriate to classify it as a low distortion wide angle lens rather than a fisheye lens.

Q: What does the IRCF specification mean?
A: IRCF refers to an infrared cut filter. It blocks infrared wavelengths from reaching the image sensor. The presence of IRCF does not mean that the lens itself is IR corrected.

Q: What camera applications can use this lens?
A: The lens can be considered for compact machine vision, embedded monitoring, robotic vision, industrial imaging, and other camera systems requiring high resolution, wide FOV, and controlled distortion.

Q: What is the mount of this lens?
A: The lens uses an M8×0.35 mount, making it suitable for miniature camera modules and compact optical assemblies.
