ri-scope® L Retinoscopes

Renowned optics to measure refraction

     

ri-scope® L retinoscope –  a premium, hand-held instrument with renowned optics and reduced reflection, available with Xenon illumination and a wide range of power supply options. Errors of refraction, such as short and long-sightedness, as well as astigmatism can be recognised and determined.

     

Two models are available:

  • The spot-light retinoscope projects a circular light beam.
  • The slit-light retinoscope with a light beam in the form of a line, simplifies   recognition and the determination of astigmatic refractive errors. The reflex in the form of a line is moved vertically to the axis across the pupils of the patient with a slight oscillating movement. The shadow moves in the same or opposite direction.
    Co-movement (plus lines): The patient is long-sighted.
    Counter-movement (minus lines): The patient is short-sighted.
  • Simple operation with knurled thumb screw. The line and spot image can be focussed with the operating element and turned 360º, angle can be read off the integrated scale.
  • Holder for hanging and fixing the fixation card into position for dynamic retinoscopy.
  • Two fixation cards supplied. The patient’s eye can adjust optimally to the distance to the retinoscope.
  • Integrated eyeglass protection.
  • Bayonet fitting for fast and secure attachment to the handle.
  • Dust-tight, very sturdy and light casing made of impact resistant plastic.
  • Simple exchange of the lamp at the base of the instrument head.
  • Xenon illumination (3.200K)
    • excellent colour rendering close to natural daylight conditions for more efficient diagnosis
  • Energy efficiency with Li-ion batteries
    • 20 hours operational lifecycle with fully charged Li-Ion battery
    • Rechargeable battery lifetime: up to 1.200 charging cycles.
