11720-L | Coaxial Ophthalmoscope

• LED light for true tissue colour and consistent, long-lasting performance.
• The coaxial optics produce a shadow-free spotlight, easier entry into undilated pupils and a larger field of view compared to standard ophthalmoscopes.
• 6apertures:
  • Micro - allows quick entry into small, undilated pupils.
  • Small - provides excellent view of fundus through an undilated pupil.
  • Large - general examination of the eye through dilated pupil.
  • Fixation - graduated cross-hairs for measuring eccentric fixation or locating lesions.
  • Slit - used to determine levels of lesions and tumors.
  • Cobalt blue - used with flourescein dye to view small lesions, abrasions and foreign objects on the cornea.
• 2 filters can be used in conjunction with any of the above apertures:
  • Red-Free filter - filters out red light for easy identification of veins, arteries and nerve fibers.
  • Polarising filter - virtually eliminates corneal reflection.
• 28 focusing lenses with a range of -25 to +40 diopters, adjustable via easy-to-reach maywheel.
• Rubber brow-rest prevents scratching of eyeglasses.
• Variable illumination strength via the handle rheostat dial.

Aperture Selection Disc
