Isobeam Fusion TM Jan 23, 2008

The new Isobeam Fusion TM Collimator from LightPath protects marking fibre lasers working at high peak power by suppressing back reflection and backscattering.

These high power beam delivery systems combine an integrated optical isolator in line with a Fusion TM fibre collimator. The 1064nm high power isolator features very low insertion loss, high isolation, high power handling, minimal return loss and excellent reliability and environmental stability. The collimator features LightPath’s Fibre Fusion technology – the lens is laser fused directly to the tip of the fibre. This virtually eliminates back-reflections without the need to angle cleave the fibre, thus allowing the optical system to remain coaxial through the isolator. Return loss is kept very low and the overall reliability of the assembly is greatly increased.

Standard configurations are available for 0.5mm and 1.0mm beam diameters. Custom designs can also be produced with different beam diameters, fibre types, higher power handing capability and further options.
