Telecommunications applications for NSG America's filter-on-lens technology include WDMs, couplers, pump combiners, multiplexers and demux monitors. The company uses this technology to coat its Selfoc microlenses with an optical thin-film interference filter. The filter is always perpendicular to the lens, which eliminates the need for alignment. This process results in a low-insertion-loss assembly, fewer component parts and fewer processing steps.
