ABSTRACT:
An apparatus is disclosed to optically determine which of four fluorophores is attached to a band of DNA molecules on an electrophoresis gel. The apparatus includes four separate band pass interference filters and four wedge prisms to create four discrete areas of light on a detector. Digital comparison of the relative intensity of light sensed in the four discrete areas determines the identity of the excited fluorophore.
