For "hands off" operation, OFR's no-moving-parts Broadband Fixed Isolators do not need to be readjusted when the wavelength changes. These Isolators are equipped with the Polarizers indicated below. In addition, most Isolators can be ordered as Faraday Rotators without Polarizers, in which case terminate Isolator Part Number with -I.

See page IO-3 for a description of Polarizers and their safe power limitations. Unless otherwise specified at time of order, these Isolators are set for horizontal input polarization. Output polarization is vertical, or can be rotated with an OFR Polarization Rotator. See Retarders on page IO-14 for specifications and ordering information.

All surfaces are AR coated for maximum transmittance, and tilted to the optic axis.

Adjustable Broadband or Fixed Broadband?

Broadband Adjustable (ex. IO-5-NIR)

  • Most wavelength flexibility
  • As much as 200 nm adjustable range
  • Very useful with different lasers
  • Lower cost
  • Higher isolation by 3 - 5 dB
  • Better transmittance by 1 - 2%

Broadband (ex. IO-5BB-800-LP)

  • "Hands off", no adjustment required
  • As much as 80 nm passband
  • Use with many λ's simultaneously
  • Operation where adjustment is not practical
  • Especially usefull with tunable lasers
