Frequently Asked Questions
Q: What makes a <1% TV distortion profile critical for this lens?
A: Standard wide-angle lenses suffer from severe barrel distortion where straight edges appear curved. A profile under 1% means the image is virtually distortion-free, allowing AI vision algorithms and mapping software to measure distances accurately without CPU-heavy digital lens corrections.
Q: Why is an 8G all-glass structure better than hybrid or plastic options?
A: Plastic components can slightly deform or shift focus when exposed to heat. An 8G all-glass construction provides excellent thermal stability, ensuring the camera stays in sharp 8MP focus under direct outdoor sunlight, harsh factory environments, or high automotive temperatures.
Q: Can this 1/2.5″ lens be used on a smaller 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.
Q: What is the benefit of the integrated IRF (IR-cut filter)?
A: The built-in Infrared Cut Filter (IRF) 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 inspection and outdoor mapping.
Q: How close can an object be for this lens to achieve sharp focus?
A: The Minimum Object Distance (M.O.D.) is 0.1 meters (10 cm). This exceptionally short working distance allows the lens to achieve ultra-sharp focus on nearby objects or passing targets, making it highly effective for macro inspection and conveyor belt tracking.
Q: Is the F2.8 aperture suitable for outdoor or factory lighting conditions?
A: Yes, an F2.8 aperture strikes a perfect balance. 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, while still letting in ample light for 8MP high-speed sensors.
