The FTS-1WS is designed specifically for an obsolete Luxeon LED. This lens is not compatible with the Rebel line of LEDs. We are no longer stocking the FTS-1WS, however it is still available to order.

To get the best optical performance from the Fraen Fiber Light Injector, the injector needs to be set at a specific mechanical position on the Luxeon LED. In order to achieve this position, this Fraen ring spacer needs to be placed between the Lambertian Luxeon LED and the lens.

This spacer is specifically designed for the following LEDs:

• Luxeon I lambertian star/emitter
• Luxeon III lambertian emitter
• Luxeon V lambertian emitter
