日本安立光衰減器
THE MN9002A is a standard optical attenuators witch has an optical system with excellentreflection,polarizationstability character-istics.Highly accurate optical attenuations attained because the MN9002A has been calibraded to an attenuation standard which uses Anritus proprietary optical-chopping system.Special plug-in uniits allow attenuations of 0 to 60dB for wavelenght of 1.31 to 1.55um,respectively.The MN9002A can be also be used as a programmable optical attenuator for optical calibration. systems since it has aGPIB. interface.
