Oftalmologilinse VOLK 60D
VOLK Aspheric lens
Aspheric surface corrects the aberrations present in more common spherical lenses, which helps to improve the field of view for diagnosis. Volk’s double-aspheric lenses eliminate more distortion for better overall imaging.
- Lenses with a higher Dioptre power provides a wider field of view, lower magnification, and the best performance through small pupils.
- Lenses with a lower Dioptre power have a narrower field of view, higher magnification, and do not perform well through a small pupil.
Lens Orientation
Double aspheric lenses are not always symmetric on both sides. A lens with asymmetric aspheres will produce different optical results depending on which side of the lens you look through. The Volk “V” is like an arrow and is designed to point towards the patient. Some lenses have a silver rim on one side of the ring – it should always be on the side of the lens closest to the patient.
