PC controlled Fiber Optic Attenuators for Tunable Laser Feb 11, 2009

it is an easy to use equipment for the continuous,automatic attenuation of the laser output power.It is based on the combination of a 1/2 wave-plate and polarizer. The algorithm used to control power operates in a closed loop with PID feedback,compensating for slow changes in output power.we also have related attenuators include lc fiber attenuator,sc fiber attenuator and fc fiber attenuator. This PC controlled attenuator is capable of attenuating light by a factor of 1000 while still maintaining an error of less than 10%,suitable for laser wavelength ranging from 410nm to 1090nm.
