Tornos Series 500 nm - 1030 nm Medium Power Wavelength Tunable Optical Isolators

EOT’s Tornos Series Faraday Rotators 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. When placed between crossed polarizers, a Faraday rotator becomes an optical isolator. An optical isolator provides high transmission in the forward direction and strongly attenuates any light traveling in the reverse direction, effectively protecting laser diodes from the deleterious effects of back reflections. Tornos Series optical isolators can be ordered with dichroic glass polarizers to minimize the size of the devices for low power applications or they can be ordered with polarizing beam splitter cube polarizers for applications where maximum transmission is required and power levels do not permit the use of dichroic glass polarizers. By aligning the output polarizer orthogonal to the backward traveling light, isolation can be maximized within the usable wavelength range of the optical isolator.

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

*If in Japan, please contact EOT directly for pricing and availability.

Notes:

  • All products are RoHS compliant.
  • Product specifications and pricing subject to change without notice.
  • Operating Temperature: Performance of EOT’s Optical Isolators is related to operating temperature. For more information, please contact EOT.
  • Escape Ports: Escape ports for EOT’s Wavelength Tunable Optical Isolators are only available when cemented PBS cubes are ordered. Wavelength Tunable Isolators with PBS cubes come standard with double escape ports on both the input and output polarizer assemblies. These escape ports can be adjusted by the customer to be either open or closed. If rejected average power exceeds 0.5W or rejected energy exceeds 0.3mJ, EOT recommends the escape ports be used. Failure to use the escape ports under these conditions could result in optical damage or degrade the performance of your isolator. Please consult EOT’s User Guide on how to use the escape ports.
  • For incident powers >2KW/cm2 or >1J/cm2 for a 10ns pulse, you may contact EOT’s sales department at sales@eotech.com or view our Custom Products page on this website.
  • Storage Temperature: Storage temperatures should not exceed 70°C. 
  • For mounting options, please reference the 500-1030nm Medium Power Wavelength Tunable Optical Isolators User Guide.
