| 摘要 |
This invention proposes a device for exciting fluorescent samples using visible light or ultraviolet light, the device comprising, a transparent plate or strip as waveguide for guiding light; at least one lighting source placed alongside the transparent plate or strip; a transparent matrix; such that the fluorescent samples in the transparent matrix placed on waveguide of the device is excited by the light refracted from the waveguide to the transparent matrix according the Snell's Law; thus the exciting S/N ratio can be improved by the light refraction of the device; wherein the light emitted from the light source with a primary incident angle larger than the critical angle of transparent plate or strip:air, but smaller than the critical angle of transparent plate or strip:matrix. |
