Features and benefits

  • Available with XL 3.5 V xenon lamp or 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. 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.

    • Counter-movement (minus lines): The patient is near-sighted.

  • 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

  • Bayonet fitting for quick and secure attachment to the handle

  • Dust-proof, very sturdy and light casing made of impact-resistant ABS plastic
