CCTV Lens – CCL11803610MPMT

CCL11803610MPMT is 1/1.8″ 3.6-10mm CCTV lens, 3-megapixel high resolution, fixed aperture F1.5~F2.8, stepping – motor – driven focus and zoom, IR-corrected.

1/1.8″ 3MP 3.6–10mm IR Corrected φ14 Motorized Zoom CCTV Lens

This 1/1.8″ 3MP 3.6–10mm motorized zoom CCTV lens is designed for compact camera systems requiring wide-angle coverage, flexible focal-length adjustment, and IR-corrected optical performance. With a 106°–41° horizontal FOV, F1.5–F2.8 aperture, φ14 mount, and stepping-motor-driven zoom and focus, it provides electronically controllable framing and focusing for surveillance and other automated imaging applications.

IR Corrected CCTV Lens Highlights at a Glance

• 3.6–10mm motorized zoom range provides flexible adjustment between wide-area coverage and narrower scene framing
• 106° horizontal FOV at the wide end supports broad scene monitoring
• F1.5–F2.8 aperture range provides useful light-gathering capability across the zoom range
• Stepping-motor-driven zoom and focus enables electronically controlled optical adjustment
• IR-corrected design helps maintain more consistent focus when switching between visible and near-infrared imaging

IR Corrected CCTV Lens Applications

Core Application Scenes

The 3.6–10mm focal-length range provides a broad field-of-view adjustment range for camera systems where the required scene coverage may vary. At 3.6mm, the lens provides a 106° horizontal FOV, making it suitable for wide-area monitoring. At 10mm, the FOV narrows to 41°, allowing tighter framing of subjects within the monitored scene.

Unlike a conventional manually adjusted zoom lens, this model uses stepping motors for both zoom and focus. This configuration allows the optical position to be controlled electronically and can simplify integration into camera systems requiring remote or automated lens adjustment.

The F1.5–F2.8 aperture provides a relatively large optical aperture, while the IR-corrected optical design is suitable for systems that operate across visible and near-infrared wavelengths. This makes the lens particularly relevant to day/night surveillance systems where changes in illumination and IR-assisted imaging need to be considered.

The 0.3m M.O.D. provides additional flexibility when the camera needs to image relatively close subjects, while the 13.1–13.8mm F.B.F.L. specification supports optical and mechanical integration during camera design.

Frequently Asked Questions

Q1: Is this lens a motorized zoom lens?
A: Yes. Both the zoom and focus functions use stepping motors, allowing the lens to be integrated into systems requiring electronically controlled optical adjustment.

Q2: What is the focal-length range of this lens?
A: The focal-length range is 3.6–10mm. The corresponding horizontal FOV ranges from 106° to 41°.

Q3: What sensor format is this lens designed for?
A: The lens is designed for a 1/1.8″ image format and supports 3 Megapixel resolution.

Q4: What is the advantage of the 106° wide-angle FOV?
A: The 106° horizontal FOV at the 3.6mm wide end allows the camera to cover a relatively broad scene. The focal length can then be increased toward 10mm when a narrower viewing angle is required.

Q5: What does IR Corrected mean?
A: IR correction is designed to reduce wavelength-related focus differences between visible and near-infrared light, which is useful for camera systems that operate with IR illumination.

Q6: Does this lens use an automatic iris?
A: No. The iris is specified as Fixed. The aperture range is F1.5–F2.8 across the zoom range.

Q7: What is the minimum object distance?
A: The specified M.O.D. is 0.3m.

Q8: What mounting interface does this lens use?
A: The lens uses a φ14 mount. It is therefore positioned within the Other Mount Lens category rather than the M12, C-Mount, or CS-Mount categories.
