Abstract
An optical detection filter has a transmission spectrum for detecting fluorescence light of a plurality of different fluorescent dyes. In the range between 350 nm and 1000 nm, the transmission spectrum has a first stopband (S1) fromλ1 toλ2, a first passband (D1) fromλ2 toλ3, a second stopband (S2) fromλ3 toλ4, a second passband (D2) fromλ4 toλ5, a third stopband (S3) fromλ5 toλ6, and a third passband (D3) fromλ6 toλ7. The stopbands (S1,S2,S3) each have a mean transmittance of at most 0.01, typically at most 0.001 or at most 0.0001, and the passbands (D1,D2) each have a mean transmittance of at least 0.5, typically at least 0.8 or at least 0.9; wherein 350 nm≤λ1<λ2<λ3<λ4<λ5<λ6<λ7<1000 nm.
