The present invention relates to an optical system, and particularly to a compact optical system, for detecting fluorescent or luminescent signals of at least two samples. It is the object of the invention to provide a compact optical system, which allows the manufacture of a small, inexpensive and portable (handheld) real-time PCR system. The object for an optical system for detecting fluorescent or luminescent signals of at least two samples, comprising for each detection system a light source for generating excitation light, an excitation filter, whereby said excitation filter transmits the excitation light from the light source to a dichroic mirror, whereby said dichroic mirror reflects said excitation light transmitted by said excitation filter to a fluorophore in a sample and whereby the emitted light from each of the samples passes through the dichroic mirror and through an emission filter to a detector that detects said emitted light, is met by placing only one excitation filter in front of the at least two next to each other situated light sources, whereby said excitation filter transmits the excitation light beams of each light source to only one dichroic mirror, whereby said dichroic mirror reflects said excitation light beams transmitted by the excitation filter to the fluorophore in each sample and whereby the emitted light of each of the samples passes next to each other through the dichroic mirror and through only one shared emission filter to at least one detector. |
