Frequently Asked Questions

• Q: What are the main benefits of the 6G all-glass structure on this fisheye lens?A: All-glass optics maximize light throughput and resist superficial scratches. More importantly, they prevent “thermal drift” (de-focusing) when camera modules run continuously or are deployed outdoors under direct summer sun exposure, ensuring a stable focal plane from -20℃ to +85℃.
• Q: How does the <-74% distortion value affect my vision system data?A: This geometric distortion is a natural optical characteristic of extreme 160° wide-angle lenses, allowing them to map a huge dome-like environment onto a flat sensor. In practical use, this barrel-shaped image is typically flattened and corrected in real-time using backend software or SDK dewarping algorithms.
• Q: Can this 1/2.5″ lens fit smaller image sensors like 1/3″?A: Yes, absolutely. With its large 1/2.5″ format design, it easily covers smaller sensors (like 1/2.8″ or 1/3″). The field of view will crop naturally according to the sensor size, but the video will benefit from outstanding edge-to-edge sharpness.
• Q: Does this lens include an integrated filter for daytime color precision?A: Yes, it features a built-in fixed IR cut filter (IRCF) that accurately filters out ambient infrared wavelengths during daytime shooting, preventing color washing and ensuring vibrant, true-to-life images with zero pink tinting.
• Q: How is the manual focus configured on this fixed focal M12 lens?A: Focus is adjusted manually during your camera module’s assembly phase. The operator screws the lens into the M12 thread block while monitoring a live reference screen. Once peak sharpness at your target working distance is reached, it is permanently locked using a thread-locking compound or optical adhesive.
