Patented new Axial PointSource™ 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 5-times larger view of the fundus than ever before achieved with a standard     ophthalmoscope in an undilated eye.

Increases magnification by 26% over a standard ophthalmoscope.

Patented Glare Extinguishment System prevents interference from unwanted glare and     reflections.

Works with all existing Welch Allyn 3.5v power sources (battery handle or wall     transformer), saving additional investment.

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.

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 aperture dial has micro, small, and large spot sizes, a slit aperture, and red-free     filter, and cobalt blue filter with add-on corneal magnifying lens (Model 11820 only).

Welch Allyn will repair or replace, free of charge, any parts of its own manufacture proven to be defective through causes other than misuse, neglect, damage in shipment, or normal wear.
