• LED illumination for accurate tissue color and reliable, enduring performance.
• The coaxial optics deliver a shadow-free light, easier access to undilated pupils, and a broader field of view compared to traditional ophthalmoscopes.
• 6 apertures:
  • Micro - facilitates quick access to small, undilated pupils.
  • Small - offers an excellent 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 identifying 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 with a range from -25 to +40 diopters, adjustable via an easy-to-use maywheel.
• Rubber brow-rest prevents eyeglass scratches.
• Adjustable illumination intensity via the handle rheostat dial.
