Project Description

980/1064nm Polarization Maintaining Mechanical Variable Optical Attenuator

PM VOA is a useful tool for the optical components and systems test. The PM Manual Variable Optical Attenuator is designed and manufactured to reduce the output optical power, get the power suitable. It is with low insertion loss, high extinction ration, high return loss and low Adjustment Precision, The PM Attenuator is widely applied at fiber laser system.

Features Applications
·       Wide attenuation range

·       High precision

·       Low original loss

·       Compact size

 ·       Fiber communication on system test

·       Optical passive component test

·       Fiber laser

·       Fiber amplifier

·       Optics lab use

  1. Above specifications are for device without connector, and the PM VOA device is both axis working. All parameters are tested at room temperature.
  2. For devices with connectors, IL will be 0.3dB higher, RL will be 5dB lower and ER will be 2dB lower. Power transmits through the connector less than 2W.The default connector key is aligned to slow axis.
  3. If there is pulse application, please be sure to inform us of pulse energy and peak power.
