Product description

No light leaves the fiber and therefore no alignment is required, and there are no unwanted reflections. Furthermore, the output fiber pigtails may be directly integrated into beam delivery systems. Combiners are available for either 2 or 3 wavelengths: 2 wavelength combiners combine red/green, blue/green, or red/blue light. 3 wavelength combiners provide full RGB operation; enabling full-color displays.

All variants are available on a custom basis, so please contact us to discuss your specific requirements.
