Description
Capture long-distance details with exceptional accuracy using our 8MP 35mm M12 Ultra-Low Distortion Lens. Engineered for standard 1/1.8″ CMOS sensors, this professional-grade telephoto lens delivers a narrow 11.7° horizontal field of view, making it perfect for targeted, narrow-angle surveillance. Featuring a clear F2.4 aperture and a “No Filter” optical configuration, it allows both visible and near-infrared (NIR) light to pass seamlessly. With an astonishingly low distortion rating of < 0.7%, it serves as a highly precise, compact optical solution for automated machine vision inspection and intelligent transportation systems (ITS).
Key Highlights
- 35mm Telephoto Narrow Angle: Provides a focused 11.7° horizontal FOV, allowing clear license plate capture or component inspection from far working distances where standard wide lenses fail.
- Ultra-Low Geometric Distortion (< 0.7%): Eliminates visual bending and edge stretching, ensuring absolute measurement accuracy without relying on resource-heavy digital calibration algorithms.
- No-Filter Full-Pass Optical Design: Equipped without an internal IR cut filter, enabling high-sensitivity performance under 850nm/940nm infrared illumination or industrial laser profiling.
- 8MP Native Sharpness: Delivers true-to-life 8-megapixel resolution across large 1/1.8-inch image formats, preventing pixelation and maintaining contrast over long ranges.

Applications & Compatibility
Core Application Scenarios
This 8MP 35mm M12 telephoto lens is specifically optimized for long-range target positioning, multi-lane separation tracking, and high-accuracy inspection lines. It excels in Intelligent Transportation Systems (ITS) for speed enforcement cameras and Automatic Number Plate Recognition (ANPR) systems, where it can cleanly isolate single vehicle lanes from a distance. The no-filter architecture and <0.7% low distortion profile make it highly effective for Industrial Machine Vision setups, such as 3D laser profiling, steel plate defect scanning, and remote warehouse inventory tracking under specialized strobe lights. It is also well-suited for long-distance perimeter surveillance and high-altitude drone tracking where wide panoramic fields are unnecessary.

Frequently Asked Questions
- Q: What is the main benefit of a 35mm focal length in an M12 mount?
- A: A 35mm focal length acts as a narrow telephoto lens. On a 1/1.8″ sensor, it trims the field of view down to 11.7° horizontally. This lets you position your camera far away from a hazard or traffic lane while magnifying the specific target with crystal-clear 8MP resolution.
- Q: What does the “FILTER: No” configuration mean for my system?
- A: It means there is no integrated IR Cut Filter (IRCF). The lens allows both visible light and near-infrared (NIR) wavelengths to pass through. This makes it ideal for day/night dual-use setups or industrial applications employing 850nm/940nm laser or LED illumination.
- Q: Is a < 0.7% distortion rating good for measurement tasks?
- A: Yes, a distortion rate below 0.7% is considered ultra-low. It provides straight lines and highly precise geometric indexing right out of the box, making it exceptional for industrial metrology, alignment tracking, and OCR scanning.
- Q: Does this lens support auto-focusing?
- A: No, this is a manual focus lens with a fixed zoom mechanism. Once you mount it and rotate the barrel to lock focus at your required working distance (minimum 1 meter), it remains securely set, eliminating mechanical focus drift.
- Q: Will this lens fit smaller sensors like 1/2.8″ or 1/3″?
- A: Yes, it can be mounted on smaller sensors without any dark corners or vignetting. However, using a smaller sensor will reduce the field of view even further, acting as an even tighter telephoto lens.
- Q: Can this lens be utilized in high-temperature environments?
- A: Yes, the lens features a robust glass-and-metal construction. Its thermal stability prevents the optical element expansion that causes lower-quality plastic lenses to lose focus in hot industrial settings.
