  • Product Description

    The patented coaxial system of the Welch Allyn 3.5 volt coaxial ophthalmoscope head, model 11720 provides the elements you’d expect from a Welch Allyn scope such as our long lasting, consistent, cool, bright white, Halogen light that ensures you observe true tissue color on every exam, with no reflections or obstructions, but that is just the beginning. With our coaxial optical system, the axis of illumination is now coincidental with the axis of vision into the retina, which eliminates the shadows that happen with standard optics and the polarizing filter nearly eliminates corneal reflection. You will now be able to perform productive examinations with nearly any sized pupil or vitreous disorder. Our twenty eight viewing lenses, ranging from -25 to +40 diopters can be accessed with our convenient one hand selection dial, helping to compensate for refractive error, positional changes in the ophthalmoscope or changes in viewing requirements. To make examinations easier, the lens dial is illuminated allowing the medical professional to see the lens being used during the exam even in a darkened room. The versatility of this scope is unsurpassed with eighteen unique aperture filter combinations available for use in your diagnostic arsenal. The sealed optics on this unit keep out dust and debris and ensure your lenses remain pristine. Whether you’re studying the fundus, iris or cornea, this coaxial ophthalmoscope will be the most useful tool in your diagnostic arsenal. From finding foreign bodies in the cornea to detecting irregularities of the pupil, the unique characteristics of this scope will ensure you can make an accurate diagnosis.

    • Halogen HPX™ lamp provides light for true tissue color and long-lasting performance
    • Coaxial optics produce a shadow-free spot, easier entry into undilated pupils, and a larger field of view versus standard ophthalmoscopes
    • Detect corneal abrasions with cobalt blue filter
    • Polarizing filter virtually eliminates corneal reflection
    • Sealed optics keep out dust and dirt
    • 18 unique aperture/filter combinations for greater versatility
    • Red-free filter may be used with any aperture
    • 28 focusing lenses with a range of -25 to +40 diopters
