Welch Allyn WEL 11875 Corneal Viewing Lens for PanOptic Ophthalmoscope

Patented new axial pointscource optics. illumination system converges the light to a point at the cornea, allowing easy entry into small, undilated pupils. the illumination pathway then diverges to the retina, illuminating a very wide area of the fundus. viewing system enables the operator to view the illuminated area on virtually the same axis, creating the widest field-of-view attainable. provides a five-times larger view of the fundus than every before achieved with a standard ophthalmoscope in an undilated eye. increases magnification by 26 percent over a standard ophthalmoscope. patented glare extinguishment system prevents interference from unwanted glare and reflections.

• The dynamic focusing wheel adjusts the focus in a continuous, smooth action for more precise control and the optimum view with a focusing range of -20 to +20 diopters
• The patient eyecup establishes and maintains proper viewing distance, provides stabilization for the view, is a pivoting point for leverage in panning around the retina, occludes ambient light, and helps with orientation
• Works with all existing welch allyn 3.5v power sources saving additional investment
