Smooth vergennes movement operated conveniently and easily by the column control. Dynamic retinoscopy option with near fixation target.Bright, well defined streak for easy detection of reversal point. Ring rheostat for smooth and easy control of illumination and all round accessibility. Provides 2.8 X the brightness of our standard retinoscopes. Superior streak quality enables easier and quicker refractions even in patients with small pupils. The crossed linear polarising filter eliminates bothersome glare from trial lenses, helping you to perform a more precise exam. The external focusing sleeve improves comfort and manoeuvrability. The sealed optics keep the lenses cleaner for more effective exams. Welch Allyn 3.5v PanOptic Ophthalmoscope with Corneal Lens:. Welch Allyns PanOptic Ophthalmoscope is a revolutionary new concept for visualizing the fundus. Developed by Welch Allyn®, the originator of the worlds first hand-held direct-illuminating ophthalmoscope, the PanOptic Ophthalmoscope incorporates an innovative and patented new optical design called Axial PointSource TM Optics.
This enabling technology makes it easier to enter small pupils and provides a dramatically wider, more panoramic view of the fundus thats 5X larger than ever before achieved with a standard ophthalmoscope in an undilated eye. Patented new Axial Point-source Optics.
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 the operator to view the illuminated area on virtually the same axis, creating the widest field-of-view attainable. Provides a 5-times larger view of the fundus than ever before achieved with a standard ophthalmoscope in an undilated eye. Increases magnification by 26% over a standard ophthalmoscope.Patented Glare Extinguishment System prevents interference from unwanted glare and reflections. Greater working distance improves the comfort of both examiner and patient.
Works with all existing Welch Allyn 3.5v power sources (battery handle or wall transformer), saving additional investment. The patient eyecup establishes and maintains proper viewing distance, provides stabilization for the view, is a pivoting point for leverage in panning around the retina, occludes ambient light, and helps with orientation. The dynamic focusing wheel adjusts the focus in a continuous, smooth action for more precise control and the optimum view with a focusing range of -20 to +20 diopters. The aperture dial has micro, small, and large spot sizes, a slit aperture, and red-free filter, and cobalt blue filter with add-on corneal magnifying lens (Model 11820 only).(Which is beyond our Control)?
