Welch Allyn Pan Optic Opthalmoscope Head- 11820
With its 5X larger view of the fundus in an undilated eye, the new Welch Allyn PanOptic Opthalmoscope performs like a specialist's instrument, yet is affordable, easy to use, and ideal for Primary Care practitioners. How it works New Halogen HPX lamp provides bright, white light. 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 you to view the illuminated area on virtually the same axis, creating the widest field-of-view attainable Glare Extinguishment System (Patent Pending) prevents interference from unwanted glare and reflections Comes with a Coblat Blue filter with add-on magnifying lens for corneal examinations (surrogate for Woods Light/black light) This model does not have the half-moon aperature. Advantages Provides a 5X larger view of the fundus than ever before achieved with a standard ophthalmoscope in an undilated eye. Enables a 25 field-of-view vs. the standard 5 field-of-view. Increases magnification by 26% over a standard scope. Greater working distance between practitioner and patient improves comfort for all. Affordable new head is compatible with all existing Welch Allyn 3.5V battery handles and wall transformers.
