ECI offers thin films designed to reduce incident energy to any assigned value. This includes designs that demand low transmission and low back reflection at a particular wavelength region. These designs are appropriate for many fiberoptic applications where too much energy is a problem for a detector. We also offer neutral density coatings for balanced attenuation across the visible spectrum. We can supply these filters complete to your exact size requirements.
