1550 nm Optical Isolators - 1525 nm to 1575 nm
EOT’s 1525 nm to 1575 nm optical isolators rotate the plane of polarized light 45° in the forward direction and an additional 45° of non-reciprocal rotation in the reverse direction while maintaining the light's linear polarization. An optical isolator shields lasers from destabilizing and potentially destructive back-reflected light from interfaces on downstream optics or back-scattered ASE from optical amplifiers.
Based on high Verdet constant, low absorption coefficient rotating material, and developed to work with up to 20 W of average input power in the 1525 nm to 1575 nm wavelength range, these EOT isolators provide the ultimate protection for polarized lasers.

Product specifications are subject to change. All products are RoHS compliant.
a Escape ports should be used if rejected light is >1 W or 0.15 J/cm2 at 10 ns or forward light is >25 W. All stray beams should be properly terminated.
NOTE: Return loss-free working distance ≥25 mm for a collimated beam
- Completely passive; no tuning required
- All isolators contain escape ports; all rejected beams are deflected at 90°
- Optional waveplate for manipulation of polarization
