Tornos Series Compact 520 nm - 810 nm Optical Isolators

EOT’s Tornos Series Compact Optical Isolators provide high transmission in the forward direction while strongly attenuating light traveling in the reverse direction, effectively protecting laser diodes from the deleterious effects of back reflections. EOT’s Tornos Series Compact Optical Isolators allow for optimal isolation and transmission at a specific wavelength within the spectral bandwidth of the isolator.

**Please note that a waveplate is needed if you are wishing to achieve more than 45º rotation through the device.**
