Frequently Asked Questions
Q: What are the main benefits of a 7.7mm lens on a 1/4″ sensor?
A: It creates a narrower, telephoto-style 27° horizontal field of view. This layout allows your camera to zoom in on specific objects from a distance, maximizing details on small targets like barcodes or labels.
Q: Can this 5MP lens support larger 1/3″ or 1/2.8″ sensor boards?
A: No, this lens is optically calculated for a 1/4″ image format. Mounting it on a larger image sensor will result in severe vignetting or solid black corners in your video output.
Q: How does the < -1% TV distortion parameter affect my vision tracking software?
A: A TV distortion rating under -1% means geometric bending is nearly imperceptible. Your measurement software and AI algorithms can process length and grid data immediately without wasting CPU power on image flattening.
Q: What does the 2G2P lens component layout provide?
A: The 2 Glass elements provide high image clarity and excellent thermal stability to keep the lens from drifting out of focus in hot factories, while the 2 Plastic elements lower overall costs for bulk deployment.
Q: Is the iris or focal distance adjustable on this M12 hardware?
A: This model features a fixed F2.6 iris aperture. While the focal length is fixed at 7.7mm, you can adjust the focus on your target object by threading the lens body deeper or shallower into your camera’s M12 mount during assembly.
Q: Does this lens include a built-in IR cut filter for security applications?
A: The baseline model is configured for standard visible light. For night vision or specific NIR laser wavelength tasks, please speak with our technical team to arrange customized filter integration.
