Applications & Compatible Devices
Core Application Scenarios
This telephoto 45mm M12 ITS Pinhole lens is purpose-built for specialized Intelligent Transportation Systems (ITS lens deployment) including high-altitude highway enforcement, long-distance license plate recognition (LPR/ANPR), and high-speed toll gate monitoring. Its narrow 8-degree field of view and high magnification make it extremely valuable for factory automation (FA lens setups), automated optical inspection (AOI) of micro-components, and far-end Machine Vision lens defect scanning. The outstanding F1.6 light intake guarantees clean data stream delivery for high-security CCTV lens infrastructure, perimeter fence intrusion tracking, and remote automated robotic guidance systems in poor ambient lighting.

Frequently Asked Questions
- Q: Why should I choose a 45mm lens instead of a standard 4mm or 6mm M12 lens?
- A: Standard 4mm or 6mm lenses are wide-to-medium options for wide areas. This 45mm lens is a specialized telephoto lens with a narrow 8° H.F.O.V., built specifically to zoom in from long distances and isolate small targets with absolute clarity and zero geometric distortion.
- Q: How does the large F1.6 aperture help in outdoor traffic monitoring?
- A: The F1.6 aperture allows a massive amount of light to hit the sensor. This lets your camera use the ultra-fast shutter speeds required to freeze the motion of speeding vehicles at night without introducing dark or blurry frames.
- Q: Is this M12 lens compatible with professional C-mount industrial cameras?
- A: Yes, it is. While it features a native thread profile matching an M12x0.5 mount, it can easily adapt to any standard industrial C-mount or CS-mount camera by utilizing a mechanical M12-to-C/CS adapter ring.
- Q: How do I calibrate the focus on this long-focal model?
- A: This lens uses a Manual Focus interface. You calibrate it during system integration by threading the lens barrel further into or out of its holder until the desired distance achieves peak sharpness, then locking it with a set-screw or ring.
- Q: Does this lens feature an automatic or adjustable iris?
- A: No, this is a Fixed Iris lens. Keeping the aperture locked at F1.6 eliminates moving internal parts, which drastically boosts mechanical reliability and shock resistance under high-vibration outdoor or factory environments.
- Q: What is the physical advantage of the 51.2mm TTL?
- A: For an extreme 45mm telephoto optical layout, a Total Track Length of 51.2mm is highly compact. It allows you to deploy heavy-duty magnification and long-distance imaging inside highly space-restricted housings.
