The illumination system converges light to a point on the cornea, allowing easy entry into small, undilated pupils. The illumination pathway then diverges toward the retina, illuminating a very wide area of the fundus. The viewing system allows the operator to view the illuminated area on virtually the same axis, creating the widest possible field of view. It provides a view of the fundus five times greater than that previously achieved with a standard ophthalmoscope in an undilated eye. Increases magnification by 26% over a standard ophthalmoscope. Patented glare quenching system prevents interference from glare and unwanted reflections. Works with all existing Welch Allyn 3.5V power supplies (battery handle or wall transformer), saving additional investment. The patient's eyepiece establishes and maintains the proper viewing distance, provides stabilization for the view, is a pivot point for panning around the retina, occludes ambient light, and assists with orientation. The dynamic focus wheel adjusts focus in one smooth, continuous action for more precise control and optimal viewing with a focus range of -20 to +20 diopters. Aperture dial has micro, small, and large spot sizes, a slit aperture, and a red-free filter and cobalt blue filter with additional corneal magnifying lens
