VOA – Variable Optical Attenuator

Its advanced power stabilization function lets you set and maintain the output power stability even when the input power fluctuates, and is available in a range of wavelengths to suit a wide range of applications.

Its stackable, space-saving design and intuitive software controls make it a valued addition to the optical lab or test bench.

Features

Fast attenuation speed

Fast attenuation speed minimizes the down time during changes in attenuation settings to shorten your overall test time.

Built in power monitoring capability

Eliminate the need for an extra power meter with the built-in power monitoring capability. Know the actual power coming out of the attenuator all from the VOA.

 Constant power output mode

With the built-in closed-loop power monitoring, the VOA can operate in the constant power output mode to stabilize fluctuating input power.

Wide coverage of operational wavelengths

One versatile tool to cover a wide variety of applications.

Simple, intuitive operation with COHESIONUI

COHESIONUI makes it simple to control VOA from your PC or mobile device. Its cutting edge design offers a sleek modern interface, cross device compatibility, customizable views and remote network access.

USB or LAN operation

Connect with USB or LAN for simple setup and operation.

Excellent measurement correlation with our optical PXI modules

Shared product architecture lets you validate your system and test requirements in the lab, and scale up to high-volume automated production testing with the VOA PXIe module.
