Developed by Welch Allyn, the originator of the world's first hand-held direct illuminating ophthalmoscope, the PanOptic incorporates an innovative and patented new optical design called Axial PointSource Optics. This enabling technology makes it easier to enter small pupils and provides a dramatically wider, more panoramic view of the fundus that's 5X larger than ever before achieved with a standard ophthalmoscope in an undilated eye.
Model 11810 features a half-moon aperture (which provides a combination of depth perception & field of view). Please Note: Does Not Include Handle.
Allows you to see much more fundus than with the traditional ophthalmoscope, I love it.
