An instrument for processing light information to assay chemical or biological molecules is made more flexible by the use of a replaceable filter module. Several light filters, or in one embodiment dichroic mirrors, are mounted in a common module in fixed position relative to each other. The whole filter module can then be removed, and a different one inserted in its place, to change the wavelength bands of light detected by the instrument, as needed, for different applications.

Replaceable filter module

An apparatus for detecting fluorescently-labeled molecules moving in an electrophoretic separation medium. The apparatus utilizes a scanning detection system in which multiple fluorophores are efficiently and simultaneously detected using dichroic mirrors to allow simultaneous detection of fluorescently-labeled molecules in ultrathin gels labeled with several fluorophores and to permit operation at speeds ten times faster than prior art gel separations. The apparatus also utilizes a detection system where lightweight collection optics are in motion while detection optics are fixed in a remote location, thereby allowing exceptionally high-speed scanning.
