532nm single mode Mechanical Variable Optical Attenuator

The 532nm single mode Mechanical Variable Optical Attenuator is a useful tool for the optical components and systems test. The SM 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 SM Attenuator is widely applied at fiber laser system.

Features

  • Wide attenuation range
  • High precision
  • Low original loss
  • Compact size

Applications

  • Fiber communication on system test
  • Optical passive component test
  • Fiber laser
  • Fiber amplifier
  • Optics lab use

The 532nm single mode Mechanical Variable Optical Attenuator is a useful tool for the optical components and systems test.

It is with low insertion loss, high extinction ration, high return loss and low Adjustment Precision, The SM Attenuator is widely applied at fiber laser system.

Both sizes of VOA are available with a hand twist or a flat-blade screwdriver. The standard size VOA uses an aluminum alloy shell, which is lighter. The nut and the screw are of elastic structure, and the adjustment torque is generated to make the mechanism self-lock, completely eliminate the transmission gap, and the transmission process is stable and five-beat. Thereby, the optical attenuation resolution is high, and the continuity, vibration resistance and stability are better.
