Optical fiber variable attenuator
A fiber variable attenuator is an optomechanical device that helps control the luminous flux between two fibers and attenuates all wavelengths of light consistently in the UV-VIS to near-infrared bands.
600um fiber at both ends,
Adjustable light attenuation 15% ~ 100%
300um fiber at both ends,
Adjustable light attenuation 5% ~ 100%
100um fiber at both ends,
Adjustable light attenuation 1% ~ 100%
Adjust the metal contact body on the right of the figure below, that is, adjust the distance between the optical fibers and control the attenuation ratio.
