Welch allyn Pan Optic Ophthalmoscope Head

Panoptic Ophthalmoscope
Features:

• 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 patient.
• Works with all existing Welch Allyn 3.5 v 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).
