1. A hand held digital documenting ophthalmoscope, comprising:

  • an illumination module for providing continuous, convergent illumination;

    an optical module configured to direct at least a portion of said illumination to an eye and to communicate return illumination from said eye through an undilated pupil of said eye, said at least a portion of said illumination directed toward said eye having an intensity below a safety limit, said optical module comprising a Maxwellian view system;

    a viewing module having an eyepiece configured to provide a true color live view to an operator of at least a portion of said eye using said return illumination;

    an electronic imager module having an imager for capturing an image of at least a portion of said eye using said return illumination;

    a mirror having a first state to provide said true color live view of at least a portion of the eye and a second state to provide said image of at least a portion of said eye;

    an illumination control apparatus configured to direct said return illumination from said eye in part to said viewing module and in part to said electronic imager module wherein said illumination control apparatus is configured to control in serial temporal fashion said return illumination directed in part to said viewing module and in part to said electronic imager module, such that direct viewing occurs during a first time interval and electronic imaging occurs during a second time interval, wherein said first and second time intervals do not substantially overlap and in which an integration time of said electronic imager module is selectively adjustable; and
