The field of application of PM elements has expanded beyond traditional markets to brand new ones, from research to industrial environments: Biomedicine, Spectroscopy, Metrology, Sensorics, Telecommunications, Lasertechnology, Surveillance & Security, Lithography.
DIAMOND supplies high-quality solutions to polarization maintaining (PM) and polarizing (PZ) fiber optical interfaces for optimal control of the signal’s polarization state. Low insertion losses (IL) combined with high polarization extinction ratios (PER) and higher return losses (RL) are achieved over very broad spectral ranges thanks to a combination of accurate optical and mechanical design.
【Features】
■Ultra Low Insertion Loss
■Ultra High PER (Polarization Extinction Ratio)
■Wide Variety of Connectors
■Wide Variety of Cables and Fibers (PANDA and Bow-tie Fibers)
