The Principal Point is a key concept in lens optics, marking the point on a lens's optical axis where light passes without deviation. It differs from the focal point and is crucial for image formation and quality. Understanding the Principal Point is essential for designing optical instruments like cameras and telescopes, and it plays a significant role in optical physics techniques, impacting image resolution and focus.
