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]
