SICK Accessories: Reflectors and optics Spacer ring

A spacer ring is an essential accessory used in optical systems to maintain the correct distance between components, such as lenses, sensors, or reflectors. This accessory ensures proper alignment and positioning, preventing distortion or misalignment that could affect the system's performance. Spacer rings are commonly used with optics like C-mount lenses to achieve the desired focal length and clarity. In addition, they help to fine-tune the optical setup in applications such as machine vision, imaging, and precision measurement, ensuring optimal functionality and image quality.
