Frequently Asked Questions
Q: What makes the 0.01m Minimum Object Distance (M.O.D.) special?
A: Most wide-angle M12 lenses cannot focus on objects closer than 10cm or 20cm without blurring. An M.O.D. of 0.01m (1cm) means this lens can be positioned almost touching a circuit board, document, or biological sample and still achieve a perfectly sharp image, which is a major advantage for macro industrial scanning.
Q: How does a wide 102° field of view achieve less than 1% distortion?
A: Standard wide-angle lenses suffer from fish-eye distortion where straight lines curve aggressively. This lens utilizes high-precision optical element mapping to correct incoming light rays, keeping geometric distortion under 1% so that rectangles and lines remain flat and true-to-life on the sensor.
Q: What is the benefit of the integrated IR-cut filter?
A: The built-in IR-cut filter blocks unwanted infrared light wavelengths during daylight hours. This prevents the camera sensor from suffering color distortion or red tints, ensuring color-accurate imaging for commercial and automated scanning systems.
Q: Can I use this 1/2.5″ lens on a 1/3″ sensor module?
A: Yes, it is fully backward-compatible with smaller sensors like 1/2.7″, 1/2.8″, and 1/3″ models. When paired with a smaller sensor, your field of view will simply narrow slightly due to the sensor crop factor, but you will experience outstanding center sharpness and completely zero corner vignetting.
Q: Is the F4.0 aperture suitable for my vision system?
A: An F4.0 aperture is ideal for industrial environments, automated factories, and well-lit kiosks. It provides a deeper depth of field (DoF), meaning a larger vertical zone in front of the camera remains perfectly in focus at the same time, reducing the need for constant refocusing.
Q: What does the “6E” configuration signify?
A: “6E” refers to a robust six-element optical layout designed to maximize resolution and eliminate optical aberrations. This premium construction ensures that the 5-Megapixel clarity is sharp from the absolute center to the very corners of your image.
