Frequently Asked Questions
Q1: What makes a “Low Distortion Lens” critical for machine vision?
Standard wide-angle lenses suffer from barrel distortion, stretching images at the borders. A low distortion lens (with TV distortion <0.5%) ensures that lines stay straight, allowing AI vision algorithms to measure and identify objects accurately.
Q2: Is this M12 lens compatible with smaller sensor sizes like 1/3″?
Yes, it is perfectly compatible. When used on smaller 1/3” or 1/2.8” sensors, it will simply result in a narrower crop of the Field of View (FOV) while maintaining identical sharpness and crisp 12.5MP fidelity.
Q3: Does this 3.65mm lens include an integrated IR cut filter?
Yes, the lens architecture uses a 6E+IRF construction, which includes a built-in Infrared Filter (IRF). This blocks unwanted infrared light to guarantee vivid, true-to-life color reproduction during daylight hours.
Q4: Can this lens withstand industrial vibration on drones or robot arms?
Absolutely. The lens utilizes a robust fixed-iris design and M12x0.5 thread. Once locked into your camera housing with a locking ring or adhesive, it resists mechanical shifts caused by high-speed motion or motor vibrations.
Q5: What is the Minimum Object Distance (M.O.D.) for macro inspections?
The M.O.D. is 0.1 meters (10cm). This close-focusing capability makes it exceptionally suited for close-range industrial PCB inspection, desktop scanning, and medical device imaging.
