Patent ID: 8705030

Claim:
An optical sample detection system, comprising: a light source; a convergence projection component configured for converging light rays emitted by the light source, the convergence projection component comprising: a front optical system; a rear optical system; and an optical stop disposed between the front and rear optical systems, wherein an angle between a normal of an internal surface of the optical stop and an optical axis in a light beam propagation direction is greater than 90° such that stray light incident to the internal surface of the optical stop is refracted away from the rear optical system; a sample accommodation component configured for accommodating a detected sample; a light beam collection component configured for receiving light rays carrying sample information from the sample accommodation component; a light splitting component configured for splitting polychromatic lights collected by the light beam collection component into independent spectrums or spectral bands; and a photoelectric detection component configured for receiving optical signals of different wavelengths separated through the light splitting component.
