Description of Biconvex, Aspheric, Aplanatic, Achromatic Lenses:
![]() |
Biconvex lens: Distinguished by two spherical (convex)
surfaces. Used in large field, low power reading magnifiers. Magnification
usually up to 4X.
Aspheric Lens: Aspheric curves allow higher magnification with
less distortion. Used by holding the more convex side (side with imprint)
towards the eye. Magnification up to 12X.
Aplanatic Lens: Consists of two equally strong plano-convex
lenses. The convex sides are arranged face-to-face. Full image is clearly
defined and free of distortion. Magnification up to 20X. (Magnification up to 4X
useful for persons with macular degeneration.)
Achromatic Lens: Top quality lens. A color-corrected lens
system that guarantees a clear, sharp image. Completely distortion free.
Magnification up to 25X.
