High Precision Electronically Controlled Optical Attenuator

The High Precision Series VOA is based on a micro-electro-mechanical system (MEMS) device platform driven by a mini-motor integrated with an optical position sensor. It uniquely offers advantageous performances that are unmatched in the industry. It features ultra-broadband from 200 to 2500nm, ultra-low insertion loss of less than 0.2dB, ultra-high setting precision, high optical power handling, and latching function. Once, the VOA attenuation value is set, it will latch to and remain at the value regardless of the environment variations and the loss of electrical power. It is available with all types of fibres having a 125 micron outer diameter.
The VOA is driven by a attached PCB having USB or RS232 computer interfaces with GUI software. A USB connection will provide sufficient power for the device. A wall-mount 12V DC supply is provided for RS232 function.
