1/1.8″ 6MP 3.5-10mm IR Corrected Manual Zoom CCTV Lens

This 1/1.8″ 6MP manual zoom CCTV lens features a 3.5–10mm focal length, F1.8 aperture, 117°–42° horizontal FOV, and IR-corrected optical design. Its wide-angle coverage and flexible manual zoom make it suitable for security cameras and compact surveillance systems requiring adjustable scene coverage.

IR Corrected Wide Angle CCTV Lens Highlights at a Glance

• 3.5–10mm manual zoom provides flexible framing from wide-area coverage to tighter scenes.
• 117° wide-angle FOV helps capture larger monitoring areas at the 3.5mm setting.
• 6MP optical resolution supports detailed surveillance imaging with 1/1.8″ sensors.
• F1.8 aperture provides strong light-gathering capability for indoor and outdoor surveillance scenes.
• IR-corrected optical design helps maintain focus consistency across visible and near-infrared imaging.

IR Corrected Wide Angle CCTV Lens Applications

Core Application Scenes

This 1/1.8″ 6MP wide-angle IR corrected CCTV lens is designed for surveillance systems where the camera needs both broad scene coverage and manual framing flexibility. Its 3.5mm wide-angle setting provides a horizontal FOV of up to 117°, making it suitable for monitoring entrances, corridors, retail areas, building interiors, and other locations where a broad field of view is important.

The 3.5–10mm focal length range also allows installers to adjust the viewing composition according to the actual installation distance. At the wider end, the lens can cover a larger area, while the longer focal length provides a narrower view for more concentrated monitoring. This makes the lens practical for security cameras that need flexible scene adjustment without replacing the optical assembly.

The IR-corrected design is particularly useful for surveillance cameras equipped with near-infrared illumination. By maintaining better optical performance when the imaging system transitions between visible and infrared wavelengths, the lens can support more consistent day-and-night surveillance performance.

For systems using larger 1/1.8″ sensors, the 6MP resolution and F1.8 aperture provide a suitable combination for detailed monitoring while maintaining a relatively wide viewing angle. For broader system-level selection, users can also refer to Towin’s CCTV Lens product range and Lens Selection Guide.

Frequently Asked Questions

Q: What type of camera is this lens designed for?
A: This lens is designed primarily for CCTV and security camera systems using 1/1.8″ image sensors. Its 6MP resolution, wide-angle coverage, and manual zoom make it suitable for adjustable surveillance applications.

Q: What is the focal length range of this CCTV lens?
A: The lens provides a 3.5–10mm focal length range. The 3.5mm setting provides a 117° horizontal FOV, while the 10mm setting narrows the horizontal FOV to approximately 42°.

Q: Is this a fixed focal lens?
A: No. This is a manual zoom lens. Its focal length can be manually adjusted from 3.5mm to 10mm to change the camera’s viewing angle and scene composition.

Q: Is this lens suitable for infrared surveillance?
A: Yes. The lens is IR corrected and is designed to support imaging systems that use near-infrared illumination, making it suitable for day-and-night CCTV applications.

Q: What sensor size does this lens support?
A: The specified image format is 1/1.8″. The optical design is intended for cameras using a 1/1.8″ image sensor with up to 6MP resolution.

Q: What is the minimum object distance of this lens?
A: The specified M.O.D. is 0.3m, allowing the lens to focus on subjects from approximately 0.3 meters away under the specified optical configuration.

Q: Does the lens have an adjustable aperture?
A: No. The lens uses a fixed F1.8 aperture and a fixed iris configuration.

Q: Can Towin customize this lens for a specific camera project?
A: Towin can evaluate customization requirements such as optical performance, mechanical interfaces, coatings, housing dimensions, and other project-specific requirements. For OEM or ODM discussions, please contact the Towin optical engineering team with your camera and application requirements.
