Patented new Axial Point Source� 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.
Greater working distance improves the comfort of both examiner and
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
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).
