Description
This high-performance 3MP Varifocal Lens is engineered for precision and versatility, featuring a versatile 4.5-18mm focal length and a robust C-Mount interface. Designed to support 1/1.8″ image sensors, it delivers exceptional clarity and a wide-angle field of view (up to 137°), making it a top-tier choice for Machine Vision, Industrial Lens applications, and Intelligent Traffic Systems (ITS).
Scenario-Based Functional Descriptions
Versatile 4X Optical Zoom for Flexible Deployment:
With a 4.5-18mm varifocal range, this lens allows users to manually adjust the focal length to capture the perfect frame. Whether you need a Wide Angle Lens for large-area monitoring or a narrower view for detailed inspection, this single lens covers multiple installation requirements, significantly reducing inventory costs for CCTV Lens integrators.
F1.4 Large Aperture & IR Correction for 24/7 Clarity:
Equipped with a bright F1.4 aperture, this lens excels in low-light environments by maximizing light intake. As an IR Corrected Lens, it eliminates focus shift when switching between daylight and infrared light, ensuring sharp, high-contrast 3-Megapixel imagery around the clock—ideal for Varifocal Day & Night Lens applications in outdoor surveillance.
Manual Precision for Industrial & FA Excellence:
Designed for stability and accuracy, the manual Iris, Focus, and Zoom rings allow for fine-tuned control in static environments. This makes it a dependable FA Lens (Factory Automation) and Industrial Lens, where consistent optical performance is critical for quality control, parts inspection, and automated assembly lines.
Optimized for Large Format 1/1.8″ Sensors:
Specifically designed to match 1/1.8″ image formats, this lens provides superior edge-to-edge sharpness compared to standard 1/2″ or 1/3″ lenses. Its high resolution and low distortion make it a preferred C-Mount Lens for high-end Machine Vision cameras and smart city AI perception.

FAQs
Q: Why is IR Correction important for this lens?
A: Most lenses experience “focus shift” when light changes from visible to infrared at night. This IR Corrected Lens uses specialized optical glass to ensure the focal plane remains the same, keeping your 3MP images crisp 24/7 without manual readjustment.
Q: Can this lens be used with 1/2″ or 1/2.8″ sensors?
A: Yes. Since it is designed for a larger 1/1.8″ format, it is fully backward compatible with smaller sensors (like 1/2″, 1/2.5″, or 1/3″) without any vignetting, often providing even better corner sharpness on smaller sensors.
Q: Is this lens suitable for high-speed traffic monitoring (ITS)?
A: Absolutely. The combination of 3MP resolution, F1.4 large aperture, and C-mount durability makes it perfect for capturing license plates and vehicle details in various lighting conditions.
