SICK Accessories: Reflectors and optics Spacer

A spacer in the context of reflectors and optics is an accessory used to maintain a specific distance between two optical components, such as a lens and a sensor or between lenses in optical systems. Spacers are essential in ensuring correct alignment, focal length, and optical performance. They can be made of materials like metal or plastic and come in various thicknesses to suit different optical configurations. Spacers help prevent misalignment, reduce optical distortion, and improve the accuracy of measurements in imaging and inspection systems.
