SICK Accessories: Reflectors and optics Spacer

A spacer is an essential accessory used in optical and imaging systems to create a precise gap or distance between components such as lenses, cameras, or sensors. Typically made from materials like aluminum, stainless steel, or plastic, spacers are designed to maintain correct alignment and working distances between optical elements, ensuring optimal performance and image quality. In machine vision, microscopy, or other precision applications, spacers help in adjusting focus, field of view, or the working distance, contributing to the system's overall accuracy and functionality.
