Abstract:
1. An imager comprising: a body; an image sensor supported by the body wherein the body is releasably operably coupleable to a module, the module having an optical aperture extending therethrough that aligns with the image sensor when operably coupled to the body to form an imaging channel and wherein the sensor is operable to image a subject within an optical axis of the imaging channel; and a camera lens configured to focus a subject image on the image sensor; a projection means for emitting radiation along the imaging channel for radiating the subject for a diagnostic purpose wherein, when the subject is an eye having a pupil, the projection means is arranged or operable to image red and infrared reflex of the eye, and wherein the projection means includes a beam splitter received within the aperture, a first radiation emitting means emitting radiation in a first wavelength positioned normal to the plane of the aperture, a second radiation emitting means emitting radiation in a second wavelength positioned parallel to the plane of the aperture, and a dichroic filter positioned between the first radiation means and the second radiation means, the dichroic filter and beam-splitter being operable to couple radiation emitted in the first wavelength to radiation emitted in the second wavelength and direct the coupled radiation along the imaging channel into the pupil of the eye.
