CS-C Mount Adaptor Ring For Machine Vision Lens

What is an Adapter Ring?

An adapter ring (also known as a mount adapter, spacer ring, or extension ring) is a precision-machined component that connects lenses and cameras with different mounting systems or adjusts the flange focal distance between them. In machine vision applications, the most common type is the C-to-CS mount adapter, which provides the exact 5mm spacing needed to correctly position C-mount lenses on CS-mount cameras.

• Connection Compatibility: They allow lenses with one mount type to be used with cameras of a different mount type
• Focal Distance Adjustment: They provide the precise spacing required for proper focusing
• System Integration: They enable the use of specialized optics in various imaging setups

While the terminology varies across industries (extension ring in photography, spacer ring in industrial automation, mount converter in consumer electronics), all adapter rings serve the fundamental purpose of ensuring proper mechanical and optical alignment between imaging components.

The design of adapter rings is deceptively simple—typically a cylindrical ring with precisely machined threads—but manufacturing tolerances are critical. Even slight deviations can affect image quality, cause mounting issues, or create alignment problems that impact system performance.

In machine vision systems specifically, using the correct adapter ring is essential for achieving proper focus and maximizing the optical performance of your imaging setup.

Overview

This adapter ring solves the common focal distance discrepancy between C-mount lenses and CS-mount cameras. By adding the precise spacing needed (5mm being the standard difference), it ensures your C-mount lenses achieve proper focus when used with CS-mount camera bodies.
