Description
This premium 5.5mm CS-mount CCTV lens delivers high-performance 3MP resolution specifically optimized for wide-area coverage and high-throughput monitoring. Designed to support large 1/1.8″ image sensors, it features an ultra-bright F1.2 aperture that provides outstanding low-light imaging without reliance on digital amplification. Engineered as a robust fixed focal industrial lens, it combines an expansive 83° horizontal field of view with strict optical control, restricting geometric distortion to less than -7%. This ensures crisp, clear, and uniform edge-to-edge detailing across expansive surveillance zones and high-speed automation systems.
Product Highlights
- Expansive 115° Wide-Angle Coverage: The 5.5mm fixed focal length delivers a broad 83° horizontal and 115° diagonal FOV, allowing single-camera setups to monitor multi-lane traffic or massive warehouse floors without blind spots.
- Superior Large-Target 1/1.8″ Format: Fully optimized for high-end 1/1.8″ sensors, capturing more light and delivering higher pixel density, better dynamic range, and richer image detail than standard 1/3″ lenses.
- Ultra-Bright F1.2 Fixed Iris: The massive F1.2 aperture ensures maximum light transmission, drastically improving color accuracy and lowering image noise in pitch-black or unpredictable low-light conditions.
- Advanced Low-Distortion Control: Despite its wide-angle capabilities, the optical layout limits optical distortion to <-7%, preventing severe barrel curving and maintaining structural integrity for data-sensitive visual inspections.

Frequently Asked Questions
Q: Why does this lens perform better on a 1/1.8″ sensor compared to a 1/3″ sensor?
A: A 1/1.8″ sensor has a larger surface area. This 5.5mm wide angle lens is optically designed to project a larger image circle, allowing you to maximize the sensor’s full resolution, field of view, and low-light capabilities without vignetting or dark corners.

Q: What is the benefit of a fixed F1.2 iris over an adjustable manual iris lens?
A: A fixed F1.2 aperture optimizes internal lens space, minimizes physical moving parts, and locks the lens at its maximum light-gathering state. This ensures lower hardware failure rates in high-vibration industrial settings while guaranteeing maximum night-vision efficiency.

Q: Will this 83° horizontal field of view cause extreme “fisheye” curving on the edges?
A: No. Standard fisheye lenses often feature distortion exceeding 30% to 50%. This professional machine vision lens utilizes precise optical engineering to hold distortion below -7%, ensuring straight structural lines stay relatively flat.

Q: Can I adjust the focus on this lens, or is it completely fixed?
A: While the focal length (5.5mm) and zoom are fixed, the focus itself is completely adjustable. It features a precise manual focus ring so you can pin-point clarity based on the exact distance to your target zone.

Q: What are B.F.L. and TTL, and why do they matter for my system?
A: B.F.L. (Back Focal Length) is 6.95mm, which is the distance from the rear glass element to the sensor. TTL (Total Track Length) is 35.14mm, indicating the total compact length of the optical train. These metrics are crucial for custom embedding, ensuring the lens physically clears internal camera components.
