Abstract:
Apparatus for imaging a microarray, said apparatus comprising:(a) support means for holding said microarray; (b) an optical system comprising: (i) an excitation light source, (ii) an optical fiber arranged to transmit excitation light from said excitation light source to a single spot of said microarray when said carrier is held by said support means, and (iii) a collimating lens arranged to collect emission light from said test region along an emission collection path that is not coaxial with said optical fiber; (c) rastering means for rastering one of said optical system and said support means relative to the other until excitation light has been transmitted to all spots of said microarray when said carrier is held by said support means; (d) detection means for receiving emission light collected by said collimating lens and for generating a signal from each spot representative of emission light emitted by said spot; and (e) imaging means for compiling signals from all of said spots and thereby forming an image of said microarray.
