  1. Above specifications are for device without connector.
  2. For devices with connectors, IL will be 0.3dB higher, RL will be 5dB lower and ER will be 2dB lower. The default connector key is aligned to slow axis. Power transmits through the connector less than 2W.
  3. For this 1064nm Isolator, Due to high IL, it is recommended to use average power of <300mW for single stage and <200mW for dual stage. If you need higher handle power, please look for our 1064nm High power isolator.
  4. If there is pulse application, please be sure to inform us of pulse energy and peak power.
