Designed for Machine Vision and UAV Drone applications.
Frequently Asked Questions
Q1: What are the advantages of a <-0.4% distortion rate in factory automation?
Standard wide-angle lenses distort lines at the periphery. A low distortion lens with less than -0.4% distortion ensures straight lines stay perfectly straight. This eliminates the need for processor-heavy software de-warping, allowing FA lens systems to measure components instantly.
Q2: How does the F4.0 aperture benefit my vision application?
An F4.0 aperture yields a significantly deeper Depth of Field (DoF) compared to wider F2.0 lenses. This means objects moving at varying distances from the camera (such as items on a conveyor belt) all stay sharply in focus without any autofocus mechanism.
Q3: What does the “3G2P+IRF” construction mean?
It denotes a hybrid layout utilizing 3 Glass elements for core thermal resistance and sharpness, and 2 precision Molded Plastic elements to achieve the ultra-low distortion profile in a lightweight chassis. The integrated IR Filter (IRF) ensures accurate daytime color reproduction.
Q4: Can this lens handle heavy vibrations on drone gimbals or robotic arms?
Yes. Thanks to its ultra-short 21.9mm TTL, rigid fixed iris, and compact Φ14mm body, it has an incredibly low center of gravity. Once threaded into an M12 mount and locked, it resists image shift caused by high-frequency vibration.
Q5: What is the Minimum Object Distance (M.O.D.) for close-up scanning?
The M.O.D. is 0.1 meters (10cm). It can capture hyper-sharp 8MP images at very close ranges, making it an excellent match for medical desktop instruments and document scanners.
Q6: Can this 1/2.3″ format lens be used on a 1/2.7″ sensor?
Absolutely. It is fully backward compatible with 1/2.7” and 1/3” sensors. The only difference is that the field of view (FOV) will narrow slightly according to the crop factor, while the center resolution remains perfectly sharp.
