Target Applications & Compatible Devices
Core Application Scenarios
This industrial-grade 190° IR corrected fisheye lens is built for extreme monitoring environments requiring an expanded spatial field from a single sensor placement. In commercial spaces, it powers ceiling-mounted 360-degree CCTV panoramic security cameras, high-ceiling warehouse tracking, and smart video doorbells. For transportation sectors, it delivers optimal performance for ITS intelligent traffic monitoring, 360 ADAS bird’s-eye automotive arrays, and heavy machinery blind-spot safety recording. Additionally, its tight 0.1m M.O.D. renders it invaluable for drone & UAV autonomous navigation, automated guided vehicle (AGV) path mapping, and high-speed robotic machine vision sorting assemblies.

Frequently Asked Questions
Q: Why is the IR Corrected feature important for this 1.9mm lens?
A: Standard lenses suffer from focus drift when switching from daytime light to nighttime infrared light because different light wavelengths refract differently. This IR corrected lens uses specialized optics to lock the focal point on the exact same plane, guaranteeing sharp day and night video.
Q: How does the field of view (F.O.V.) change based on the sensor image circle?
A: At a full Φ5.4mm image circle coverage, this lens delivers its maximum 190° F.O.V. If your camera sensor crops the image to a Φ4.22mm field, the field of view naturally transitions to a tighter 132° F.O.V.
Q: Can this 1/1.8″ format lens fit onto a 1/2.8″ security sensor?
A: Yes, it is fully backward compatible with 1/2.7″ and 1/2.8″ sensors. However, because a smaller sensor uses a smaller area of the optical field, the outer edges of the 190° view will be cropped.
Q: What type of image processing does a -105% distortion require?
A: A -105% distortion profile generates a curved, ultra-wide fisheye circular effect. To view it as a flat rectangular video stream, your backend software or ISP will need to apply a standard de-warping algorithm.
Q: Can this lens handle close-up item inspections in factory automation?
A: Absolutely. Thanks to its 0.1m Minimum Object Distance (M.O.D.), it can easily focus on objects just 10cm away from the lens tip, making it ideal for compact robotic assembly lines.
Q: Is this lens rugged enough for external automotive installations?
A: Yes. The lens barrel is built with high-stability metal alloys that withstand weather shifts and operational vibration, maintaining strict alignment across extreme temperature cycles.
