1550 nm Rotators and Isolators
Rotate your laser’s linear polarization and/or shield your laser from back-reflected light from interfaces on downstream optics or back-scattered ASE from optical amplifiers.
These 1550 nm Rotators and Isolators are optimized for use anywhere across the 1525 nm to 1575 nm near-IR wavelength window with no tuning required. They are ideal for laser applications in LIDAR, medicine and life sciences, and remote sensing.
1550 nm Rotators and Isolators - Key Parameters
Add an optional waveplate for total flexibility in the input polarization. Isolators contain escape ports with rejected beams deflected at 90°.
