Manual Variable Optical Attenuator
Manual variable optical attenuator is a device designed to attenuate an intensity or power level of an input optical beam in a controlled manner to produce an output optical beam with different attenuated intensities.
Mechanical Variable Micro - Optics type attenuators use a mechanical method to produce attenuation. Typically light is coupled out of the fiber using a collimator lens and a precision screw mechanism blocks a portion of the light before it is coupled back in to the fiber.
We offer stable performance over wide temperature and wavelength ranges manual variable optical attenuator. They have low insertion loss and high resolution / repeatability. In addition, its compact design is excellent for mounting on panel. Specific type of connector can be built on each end.
