11820 3.5 V HALOGEN PANOPTIC OPHTHALMOSCOPE WITH COBALT BLUE FILTER AND CORNEAL VIEWING LENS

The revolutionary PanOptic Ophthalmoscope addresses the fundamental challenge in ophthalmoscopy—to get a good view of the fundus in order to make a sufficient assessment. Patented Axial PointSource Optics make it easy to enter undilated pupils, offering a 25º field of view, resulting in a view of the fundus that's 5X greater than you see with a standard ophthalmoscope in an undilated eye. Direct viewing of the fundus through the PanOptic provides better images of the retinal changes caused by hypertension, diabetic retinopathy, glaucoma, and papilledema to enable clinicians to make these diagnoses earlier.

• Fast, easy entry into undilated pupils
• Halogen HPX lamp provides bright, white light
• 5x larger view of the fundus vs. standard ophthalmoscopes in an undilated eye
• 25 degree field of view vs. the standard 5 degree field of view
• Greater working distance improves comfort for both practitioner and patient
• Helps detect corneal abrasions with cobalt blue filter and corneal viewing lens (model 11820 only)
• Patented Glare Extinguishment System prevents interference from unwanted glare and reflections
• Compatible with all existing Welch Allyn 3.5 V power sources (not included)
