         Products             PM Combiner
 

The G&H PM Combiner enables the efficient combination of two orthogonally polarised sources of light such that they are output through the same, single fibre output.

 

In optical amplifiers this provides a doubling of pump power whilst ensuring pump redundancy should a pump failure occur.

 

Applications include high power optical amplifiers and undersea systems. All ports consist of polarisation maintaining fibre.

Visible Wavelength Combiner
 

G&Hs Visible Wavelength Combiners are singlemode optical fibre components and modules. They enable any two or three primary colours in the visible wavelength region to be combined or separated.

 

Designed for applications in display systems, sensors and biomedical equipment, the combiners utilise G&Hs low loss fused fibre technology.

 

No light leaves the fibre and therefore no alignment is required; and there are no unwanted reflections. Furthermore the output fibre 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. 3 wavelength combiners provide full RGB operation; enabling full colour displays.

 

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