Abstract: An ophthalmic imaging system includes a first lens group, an illumination light source, an imaging module, a fixation light, a reflective element, at least one light-blocking member, and a first polarizer. The first lens group includes an aspheric first lens. The fixation light provides a light beam and includes at least three light-emitting components. The reflective element is configured to reflect the light beam and direct the light beam towards the aspheric first lens. The light-blocking member is disposed downstream from and in a light path of the fixation light and disposed upstream from and in a light path of the reflective element. The first polarizer is disposed downstream from and in the light path of the fixation light and disposed upstream from and in the light path of the reflective element to polarize the light beam.
