RI SCOPE F.O. RETINOSCOPE HEAD 3.5V XENON

Productbeschrijving

• The ri-scope® retinoscope (skiascope) measures the refractive power of the eye. Errors of refraction, such as in short and long-sightedness, as well as astigmatism can be recognised and determined.
• Choice of XL 3.5 V xenon lamp or HL 2.5 V halogen lamp.
• 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.
