| 主权项 | 1. An optical system for fluorescence detection comprising: two parabolic mirrors, a first parabolic mirror and a second parabolic mirror, wherein fluorescent light beams that are incident from different directions are reflected by the first parabolic mirror as parallel light beams to the second parabolic mirror and are converged at one point by the second parabolic mirror, wherein when a ratio of a pseudo focal length f2 of the second parabolic mirror to a pseudo focal length f1 of the first parabolic mirror (f2/f1) is β, and a difference between a bend angle θ2 of an optical axis bent by the second parabolic mirror and a bend angle θ1 of the optical axis bent by the first parabolic mirror (θ2−θ1) is Δθ, these quantities satisfy the following formula: Δθ=a ln β+b where: 49≦a≦60, −2≦b≦8. | ||
