Welch Allyn LED 3.5v Coaxial Ophthalmoscope (Head Only)

11720-L | Coaxial Ophthalmoscope

• LED illumination ensures accurate tissue color and delivers reliable, enduring performance.
• The coaxial optics provide a shadow-free focus, allowing easier access to undilated pupils and offering a wider field of view than traditional ophthalmoscopes.
• 6 apertures:
  • Micro - facilitates swift access to small, undilated pupils.
  • Small - offers a clear view of the fundus through an undilated pupil.
  • Large - suitable for general eye examination through a dilated pupil.
  • Fixation - features graduated cross-hairs for assessing eccentric fixation or pinpointing lesions.
  • Slit - used to evaluate the depth of lesions and tumors.
  • Cobalt blue - used with fluorescein dye to detect small lesions, abrasions, and foreign bodies on the cornea.
• 2 filters can be combined with any of the apertures:
  • Red-Free filter - removes red light to easily identify veins, arteries, and nerve fibers.
  • Polarising filter - significantly reduces corneal reflection.
• 28 focusing lenses ranging from -25 to +40 diopters, adjustable with an accessible maywheel.
• Rubber brow-rest protects eyeglasses from scratches.
• Adjustable illumination intensity via the handle rheostat dial.
