VISIBLE WAVELENGTH COUPLER
Fused Fiber Coupler
The visible wavelength coupler splits or combines light in the visible region. Versions optimised for any wavelength within the range 450 – 700 nm may be selected.
Designed for applications in display systems, sensors and biomedical equipment, the coupler utilizes Gooch & Housego’s low loss fused fiber technology.
No light leaves the fiber, therefore no alignment is required and there are no unwanted reflections. Furthermore the output fiber pigtails may be directly integrated into beam delivery systems.
For components and modules which combine different wavelengths within the visible region please refer to the datasheet visible wavelength combiners.
