Low Distortion Lens – S16011703016F67

S16011703016F67 is Low distortion 8-Megapixel CCTV lens with Built-In IR Filter, IP67 waterproof, F1.6 35° M16-mount for surveillance or industrial applications.

16mm M16 8MP Low Distortion Lens

This 16mm M16 low distortion lens is designed for 1/1.7-inch 8MP sensors such as the AR0821, delivering a controlled 35° diagonal field of view with less than -2% distortion. Its F1.6 aperture, compact 8G+IRCF optical structure, and IP67 protection make it suitable for high-resolution automotive, industrial, and embedded vision systems requiring accurate image geometry.

M16 Low Distortion Lens Core Highlights

• 16mm fixed focal length: Provides controlled scene coverage for applications requiring a narrower field of view.
• High-resolution 8MP imaging: Designed for 1/1.7-inch AR0821 sensors and detailed image capture.
• Ultra-low distortion: Less than -2% distortion helps preserve object geometry and image proportions.
• F1.6 large aperture: Provides strong light-gathering capability for variable lighting conditions.
• IP67 protection: Supports automotive and outdoor vision systems exposed to dust and water.

16mm M16 Low Distortion Lens Applications

Core Application Scenes

The combination of a 16mm focal length, 35° diagonal FOV, 8MP resolution, and distortion below -2% makes this lens particularly suitable for applications where controlled viewing coverage and accurate image geometry are more important than an extremely wide field of view.

Typical applications include:

• Automotive forward and long-range vision: The 16mm focal length provides a more concentrated viewing area than short-focal-length wide-angle lenses.
• Vehicle-mounted recognition: Low distortion helps maintain consistent object geometry for image analysis and recognition.
• Industrial inspection: The < -2% distortion specification supports applications where geometric accuracy is important.
• Machine vision positioning: A controlled 30° horizontal FOV can help isolate specific inspection areas while maintaining 8MP image detail.
• Outdoor intelligent imaging: IP67 protection allows integration into camera systems exposed to dust and water.
• Object recognition and measurement: Low optical distortion helps reduce geometric deformation in captured images.

Designed for automotive vision, industrial inspection, machine vision positioning, and high-resolution outdoor imaging applications.

For applications requiring compact optical integration, TOWIN’s M16/Mount Lens Solutions can be considered alongside other special-mount options. For low-distortion requirements, see the Low Distortion Lenses category.

Optical Design and Imaging Performance

The lens uses an 8G+IRCF optical structure. IRCF refers to an IR Cut Filter, which helps block unwanted infrared wavelengths during visible-light imaging. It should not be interpreted as an IR-corrected optical design.

The defining optical characteristic of this model is its less-than-2% distortion. Such a low distortion level helps maintain a more accurate relationship between real-world objects and their captured image positions. This can be valuable in machine vision, positioning, measurement, recognition, and automotive imaging applications.

The 16mm focal length provides a substantially narrower field of view than typical wide-angle M12 lenses. With the AR0821 sensor, the lens delivers approximately 35° diagonal, 30° horizontal, and 17° vertical FOV, allowing the camera system to focus on a more defined scene area.

The F1.6 fixed aperture provides strong light-gathering capability while maintaining a fixed optical configuration. This is useful for embedded vision systems where consistent optical behavior is preferred.

Low Distortion Performance

With distortion specified below -2%, this lens is well suited to applications where excessive barrel or pincushion distortion could affect image analysis.

Potential use cases include:

• Object dimension analysis
• Visual positioning
• Industrial inspection
• Target recognition
• Automotive object detection
• Machine vision measurement
• High-resolution scene analysis

Compared with strongly wide-angle or fisheye optics, the controlled FOV and low distortion make this lens more suitable when preserving the original geometry of the scene is a priority.

Environmental Protection

The lens features an IP67 waterproof rating, providing protection suitable for outdoor and automotive camera installations where dust and water exposure may occur.

This makes it appropriate for:

• Vehicle-mounted cameras
• Outdoor industrial cameras
• Smart transportation equipment
• Industrial inspection systems
• Embedded outdoor vision modules

The complete camera assembly should still be evaluated as a system because the final environmental protection level also depends on the housing, connector, cable, sealing, and installation structure.

Frequently Asked Questions

Q1: What sensor is this 16mm lens designed for?
A: It is designed for a 1/1.7-inch AR0821 sensor with 8MP resolution.

Q2: What is the field of view of the 16mm lens?
A: With the AR0821 sensor, the lens provides approximately 35° diagonal, 30° horizontal, and 17° vertical FOV.

Q3: Is this a low distortion lens?
A: Yes. The specified distortion is below -2%, making it suitable for applications requiring accurate image geometry.

Q4: Is this lens a wide-angle lens?
A: No. With a 35° diagonal FOV, the 16mm lens provides controlled, relatively narrow scene coverage rather than wide-angle coverage.

Q5: What are the main advantages of the 16mm focal length?
A: The 16mm focal length provides a more concentrated field of view, which can be useful for target recognition, controlled-area inspection, and automotive vision applications where excessive scene width is undesirable.

Q6: What does the IRCF in the optical structure mean?
A: IRCF means IR Cut Filter. It blocks unwanted infrared wavelengths in visible-light imaging. It does not mean the lens is optically IR corrected.

Q7: Is the lens suitable for automotive applications?
A: Yes. The IP67 waterproof construction makes it suitable for automotive and outdoor vision systems requiring protection against dust and water.

Q8: What mount does this lens use?
A: The lens uses an M16X0.5 mount, so the camera housing and mechanical interface should be designed to accommodate this mounting specification.
