Programmable Optical Attenuator


The MN938A can set attenuation in a range of 0 to 60 dB in 0.1 dB steps. Two wavelengths can be selected. As the MN938A is provided with GPIB as standard, it can be used in a variety of automatic measuring systems for development, production, and inspection. A rotary encoder permits attenuation to be set smoothly even when used manually.

  • Wide attenuation range: 0 to 60 dB
  • Application for two wavelengths by switch selection
