Welch Allyn 3.5V Coaxial Ophthalmoscope Head

The patented Welch Allyn Coaxial Vision System facilitates ophthalmoscopy by enabling easier entry into the eye, a larger field of view and reduced glare compared to standard ophthalmoscopes.

  • The Halogen HPX™ lamp provides light output for true tissue colour and consistent, long-lasting illumination
  • The coaxial optics produce a shadow-free spotlight, easier entry into undilated pupils and a larger field of view versus standard ophthalmoscopes
  • Detect corneal abrasions with the cobalt blue filter
  • The polarising filter virtually eliminates corneal reflection
  • The sealed optics keep out dust and dirt
  • 18 unique aperture/filter combinations for greater versatility
  • The red-free filter may be used with any aperture
  • 28 focusing lenses with a range of -25 to +40 diopters
  • Variable illumination strength via the rheostat dial

6 apertures:

  • Macular - allows quick entry into small, undilated pupils.
  • Intermediate - provides excellent view of fundus through an undilated pupil.
  • Wide Angle - general examination of the eye through dilated pupil.
  • Fixation-Cross - graduated cross-hairs for measuring eccentric fixation or locating lesions.
  • Slit - used to determine levels of lesions and tumors

Filters can be used in conjunction with any of the above apertures:

  • Red-Free - filters out red light for easy identification of veins, arteries and nerve fibers.
  • Cobalt blue - used with flourescein dye to view small lesions, abrasions and foreign objects on the cornea.
