850±50nm Broadband Optical Isolator

  • Wavelength: 850nm 830nm 810nm
  • Handling Power: or Custom Handling Power 500mW
  • Fiber Type: Single Mode Fiber
Product Details

  The 850nm Broadband Polarization Independent (Polarization Insensitive) Optical Fiber Isolator is an in-line pigtailed miro-optic component allows light to be transmitted only in the forward direction while blocking the backward transmittion. It features wide operating wavelength, low insertion loss. The isolators are commonly used to protect lasers or amplifiers against back-reflected light. High power available upon request.
