Abstract:
1. An instrument for amplifying and detecting nucleic acids, comprising: a device for subjecting a sample to amplification and/or nucleic acid hybrid melting reactions, wherein the device comprises a thermal cycler, and an apparatus for emitting and detecting light, comprising: wherein said rotary wheel comprises at least two excitation light sources and said control unit is configured to rotate said excitation light sources relative to the position of said first light guide, allowing at least one of said excitation light sources to emit light to one defined first light guide; wherein the rotation of said rotary wheel carrying said excitation light sources and the rotation of said rotary filter wheel of said emission module are electronically coupled and controlled by the control unit; and wherein said control unit is configured to rotate said rotary filter wheel in such a manner that for each reaction region, a filter on said rotary filter wheel having a transmission spectrum corresponding to the emission spectrum of light emitted from said reaction region when excited by excitation light is between said detector and said at least two second light guides when said reaction region is excited by said excitation light.
