Frequently Asked Questions

Q: What lens is best for machine vision?
A: The best machine vision lens depends on the application requirements, including sensor size, working distance, field of view, resolution, and lighting conditions. Common machine vision lenses include low distortion lenses, FA lenses, telecentric lenses, and wide-angle lenses for industrial inspection, robotics, and automation systems.
Q: How to choose focal length?
A: Focal length is selected based on the required field of view, sensor size, and working distance. Short focal lengths provide a wider viewing angle, while longer focal lengths offer narrower views with higher magnification. Choosing the correct focal length ensures accurate imaging performance for machine vision and industrial applications.
Q: What is low distortion lens?
A: A low distortion lens is an optical lens designed to minimize image deformation, especially near the edges of the image. It is widely used in machine vision, robotics, barcode scanning, and measurement systems where imaging accuracy and geometric consistency are critical.
Q: What is TOF lens?
A: A TOF (Time of Flight) lens is designed for depth sensing cameras that measure distance by calculating the time light takes to travel between the camera and the object. TOF lenses are commonly used in 3D imaging, facial recognition, robotics navigation, gesture recognition, and autonomous systems.
Q: What is M12 lens?
A: An M12 lens, also known as an S-mount lens, is a compact threaded lens commonly used in security cameras, robotics, automotive systems, and embedded vision applications. M12 lenses are widely valued for their small size and flexible optical configurations.
Q: What is IR-corrected lens?
A: An IR-corrected lens is designed to maintain focus consistency between visible light and infrared light, improving image clarity in day and night imaging applications such as surveillance, automotive vision, and driver monitoring systems.
Q: What is the difference between FA lens and CCTV lens?
A: FA lenses are designed for industrial machine vision applications with higher optical precision, lower distortion, and better imaging consistency compared to standard CCTV lenses, which are mainly used for general surveillance purposes.
