XtendLan CS C lens adapter

XtendLan CS/C Lens Adapter — C-mount Adapter

For users who need to combine different types of lenses and cameras, the XtendLan CS/C adapter is an essential solution. This spacer ring allows for the easy installation of C-mount lenses onto cameras designed for CS-mount lenses, thereby expanding the compatibility of your photographic or industrial imaging equipment. By adding 5 mm to the distance between the image sensor and the lens, the adapter bridges the standard gap between these two mount types. It offers a quick and reliable installation, making it a valuable tool for both industrial imaging professionals and photography enthusiasts.

Compatibility and Usage

The XtendLan CS/C adapter is designed for maximum flexibility. While most cameras on the market use CS-mount lenses, this adapter enables the use of C-mount lenses without requiring major modifications. It effectively adjusts the 12.5 mm flange focal distance of CS-mount lenses to the 17.5 mm required for C-mount lenses, ensuring optimal focus. Before purchasing, however, please check whether your camera already includes a similar adapter ring, as these can often be removed.

Specialized Use for Macro Imaging

Beyond its primary function as an adapter, this ring is also suitable for macro photography —particularly when capturing small objects in industrial settings. By stacking multiple adapters, you can create extension rings with 5 mm increments, enabling detailed imaging of very small objects—ranging from the centimeter scale down to the millimeter scale. This is particularly useful for technical applications requiring high precision.
