Patent ID: 8262224

Claim:
A binocular indirect ophthalmoscope comprising: a head wearable structure; a mounting assembly attached to the head wearable structure; an illumination housing attached to the mounting assembly, the illumination housing containing an illumination source; a viewer module coupled to the illumination housing, the viewer module comprising first and second optical paths, the first optical path directing light energy from the illumination source through an optical port to an eye under examination, the second optical path providing a reflected image from the eye to first and second viewing optical ports to allow a wearer to view the reflected image; said mounting assembly allowing said viewer module to be adjusted to the wearer's face; said mounting assembly further provided for moving said viewer module between an in-use position wherein the viewer module is adapted to be disposed in front of the wearer's face for viewing the reflected image through the viewing optical ports and out-of-use position wherein the viewer module is disposed away from the wearer's face; further comprising an optical polarizer/analyzer receiving light energy from said illumination source for providing intensity adjustment of the light energy provided to the eye under examination; said mounting assembly comprising a pivot allowing the illumination housing with attached viewer module to be moved between the in-use and out-of-use positions; wherein at least one magnet is provided for securely holding said viewer module in the in-use and out-of-use positions; and further comprising a switch for automatically completing an electrical circuit for providing electrical power to said illumination source when the viewer module is placed in the in-use position and interrupting the electrical circuit when said viewer module is placed in the out-of-use position.
