The Welch Allyn 3.5v Standard Ophthalmoscope uses halogen light for true tissue color and consistent, long-lasting illumination. It comes with 6 apertures for general and specialist use and 28 lenses from -25 to diopters for better resolution. Otoscope uses Halogen HPX Lamp and fiber optics for cool light with no reflections, no obstruction. It comes with a built-in throat illuminator/penlight and a wide-angle viewing lens for instrumentation under magnification. The Lithium-Ion (Smart) Handle is just half the weight of current 3.5v handles. It averages 120 minutes of on time between charging. It has the smallest diameter of any 3.5v power handle on the market. The textured handle is made of sturdy CYCOLOY resin. It comes with a low-battery indicator and lithium-ion battery technology that has no "memory" effect. It has a soft grip rheostat intensity control, and AC charging module with retractable prongs that is easily removable from the handle.
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.
