Abstract
A wavelength-selective mirror selector. A substantially planar wavelength-selective selective mirror holder is disposed askew to a common optical pathway. The holder has a plurality of mirrors mounted thereon and an axle attached normal thereto for rotating the holder so as to place a selected one of the mirrors in the common optical pathway. A motor is connected to the axle for rotating the mirror holder, either selectively or continuously. When a selected mirror is placed in the common optical pathway, the pathway is split so that an excitation light beam of one wavelength traveling along a source optical pathway from a light source is reflected by the mirror along the common optical pathway toward a sample, while light of a different wavelength propagating back along the common optical pathway passes through the mirror to travel along a detector optical pathway to a detector.
