Telecentric lenses are crucial in optics and vision components for their unique benefits. Unlike regular lenses, they ensure light rays hit the image sensor perpendicularly, reducing errors and distortion. They maintain consistent magnification, regardless of the object’s distance, making them perfect for tasks like machine vision and quality control. By minimizing perspective issues, these lenses enhance measurement accuracy, boosting the efficiency and precision of optical systems. In essence, telecentric lenses are key for achieving high precision and accuracy in vision components.
