The FVA-UV fiber optic variable attenuator is an opto-mechanical device that helps control the amount of light (signal) transmitted between two fibers. The FVA-UV couples to the fibers via SMA 905 connectors, with manual adjustment for attenuating light uniformly at all wavelengths from the UV-Vis through Shortwave NIR. Also available are adapters for connecting the attenuator to any light source having a collimating lens at its aperture.
