The sensor is a planar crystalline silicon waveguide , which is highly transparent , between lambda = 1 . 3 and 6 . 5 mu m , so that its operational spectral range covers most characteristic chemical absorption bands due to bonds such as C - H , N - H , O - H , C - C , N - O , C [ double bond , length as m - dash ] O , and C [ triple bond , length as m - dash ] N , as opposed to conventional UV , Vis , Near - IR sensors , which use weaker overtones of these fundamental bands .
