Abstract
Device for controlling transmission of radiation, comprises a first substrate comprising a first conductive layer; a second substrate comprising a second conductive layer; an active layer positioned between the first and second conductive layers for controlling the transmission of radiation by altering its light transmissivity dependent on a voltage applied to the first and second conductive layers; a first contact providing a first electrical connection to the first conductive layer; a first portion of an adhesive or solder for attaching a first proximal end of the first contact to the first conductive layer; a second contact providing a second electrical connection to the second conductive layer; and a second portion of adhesive or solder for attaching a second proximal end of the second contact to the first or second conductive layer.
