SICK Accessories: Reflectors and optics Spacer ring

A spacer ring is an optical accessory used to adjust the distance between components in imaging systems, such as lenses and sensors. It helps achieve the desired focal length or working distance, allowing for optimal image quality and focus. Spacer rings are commonly used in machine vision, industrial inspection, and scientific applications where precise optical alignment is required. By ensuring the correct spacing between components, spacer rings contribute to maintaining sharp focus, improving light management, and enhancing the overall performance of the optical system.
