BFI Optilas, a pan-European partner of Precision Photonics (PP), has announced a line of super-broadband, high-energy polarisers for visible to near-infrared applications.
Like BFI's selection of laser-line polarising beamsplitter cubes and beam combiners, these components utilise PP's advanced ion-beam-sputtering (IBS) coatings and Telcordia-qualified CADB epoxy-free bonding technique to provide low-loss optical components that are thermally stable and suitable for high power Nd:YAG and fibre laser applications where fluences are greater than 500mJ/cm2 and calcite or cemented cube polarisers cannot be used.
This super broadband polariser maintains more than a 500:1 extinction ratio throughout the entire visible to near-infrared (400-1,100nm) without sacrificing overall transmission (Tp more than 92 per cent) or damage threshold (more than 10J/cm2).
These fused silica beam splitters are available with a standard 1/2 x 1/2in input face and custom prism polariser assemblies will be available in sizes from 1 to 25mm and larger.
