Kit including:

  • Ri-Scope Retinoscope with Slit Lamp- Halogen 2.5V
  • Ophthalmoscope L2 - Halogen 2.5V
  • 'C' Handle 

 

The ri-scope retinoscope measures the refractive power of the eye. Refractive flaws, such as near-and far- sightedness as well as astigmatism can be detected and diagnosed.

HL 2.5-V halogen lamp,

The slit-light retinoscope with a light beam in the form of a line, simplifies detection and diagnosis of astigmatic refractive flaws.

Easy to operate with knurled thumb screw. The line and spot image can be focussed with the controls and turned 360, angle read-out displayed on the integrated scale. Holder for hanging and placement of the fixation card into position for dynamic retinoscopy. Delivered with two fixation cards. Integrated eyeglass protection. Bayonet fitting for quick and secure attachment. 

The ri-scope L ophthalmoscopes have a thumb-rest for securing the ophthalmoscope, which enables easy control of all the elements with one finger. Reflexes from the cornea and iris are avoided by separating the observational and illuminating light beams (Gullstrands’s principle).

 L2, with correction lenses with up to 89 diopter values. Easy to operate aperture hand-wheel for apertures and filters included in all three versions.

  •  HL 2.5V halogen lamp.
  • The slit-light retinoscope with a light beam in the form of a line, simplifies detection and diagnosis of astigmatic refractive flaws. 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. A shadow moves in the same or opposite direction. Co-movement (plus lines): The patient is far-sighted. Countermovement (minus lines): The patient is nearsighted.
  • Easy to operate with knurled thumb screw. The line and spot image can be focussed with the controls and turned 360, angle read-out displayed on the integrated scale.
  • Holder for hanging and placement of the fixation card into position for dynamic retinoscopy.
  • Delivered with two fixation cards. The patients eye can adjust optimally to the distance to the retinoscope.
  • Integrated eyeglass protection.
