980nm Polarization Maintaining Optical Isolator

  • Wavelength: 980nm 975nm
  • Handling Power: or Custom Handling Power 500mW
  • Fiber Type: Polarization Maintaining (PM) Panda Fiber
Product Details

  The 980nm Polarization Maintaining (PM) Fiber Isolator is an in-line miro-optic component allows light to be transmitted only in the forward direction while blocking the backward transmittion. It's built with PM Panda fiber and designed to maintain the polarization of the input light with high extinction ratio. The PM isolators are commonly used to protect lasers or amplifiers against back-reflected light. High power 980nm PM isolator availible upon request.
