Near Infrared WDM

The Near Infrared WDM enables the low loss combining or splitting of a pair of wavelengths within the 700nm to 1199nm region. G&H can rapidly produce such custom WDMs, with typical minimum wavelength separation of 50nm.

Designed for applications in fibre laser, sensing, biomedical, military and avionics the WDM utilises G&H’s low loss fused fibre technology. No light leaves the fibre and therefore no alignment is required. Furthermore the output fibre pigtails may be directly integrated into beam delivery systems.

Specific applications could include combining two sensor wavelengths onto one fibre, splitting laser harmonics,  or combining wavelengths in fibre lasers.
