Achromatic Lenses
from Artifex Engineering

The achromatic lens consists of two or more elements, usually of crown and flint glass, such that the composite element has been corrected for chromatic aberration with respect to two selected wavelengths. In these lenses, chromatic, spherical and coma aberrations are considerably reduced. These... [See More]

Aspheric Acrylic Precision Lens- Uncoated -- LAP0404
from Knight Optical Ltd.

Aspheric lens - Precision Grade.4.25mmf.l x 3.8mm aperture. Traditionally lens surfaces have been sections of a sphere. For many applications this leaves spherical aberration as the dominant defect of any image so created. Aspheric lenses are used to correct these image defects. One solution to this... [See More]
