Frequently Asked Questions
Q: What is the advantage of the F-Theta distortion profile on this 1.9mm lens?
A: Standard fisheye lenses heavily compress the image edges. An F-Theta lens ensures that the image distance from the center is directly proportional to the real-world angle (\(y=f\cdot\theta\)), making it significantly easier for machine vision and tracking algorithms to calculate spatial coordinates and de-warp the image accurately.
Q: Why is a 9G glass structure better than standard lens components?
A: The 9G structure consists of 9 premium all-glass optical elements. Glass provides far superior light transmission, higher clarity, and unmatched thermal stability compared to plastic lenses, completely preventing focus drift in extreme hot or sub-zero environments.
Q: Can this 1/2.3″ format lens be used on smaller sensors like 1/2.8″?
A: Yes, it is fully backward compatible. However, because a 1/2.8″ sensor crops the outer edges of the Φ4.5mm optical image circle, your resulting diagonal, horizontal, and vertical fields of view will be tighter than 185 degrees.
Q: Does this 9MP lens support day and night functionality?
A: Yes. This lens features advanced IR corrected optics. It prevents the focus from shifting when your system switches between daytime visible light and nighttime infrared illumination, ensuring 4K resolution 24/7.
Q: How does the 0.1m M.O.D. benefit industrial automation setups?
A: The 0.1m Minimum Object Distance allows the camera module to be placed exceptionally close (10cm) to moving production line components while maintaining crystal-clear focus, making it ideal for tight robotic sorting cages and inspection rigs.
Q: Do you offer bulk customization for the internal filters?
A: Yes, for B2B wholesale orders we can provide tailored adjustments, including integrating specific 650nm IR-cut glass, 850nm/940nm pass filters, or completely clear optical glass depending on your product matrix.
