SKU
AGL-15-AGL-20
The aspheric shape allows the lens to achieve a shorter focus with smaller spherical aberration than provided by a similar convex surface of a plano convex lens. The lens is used for squeezing small illumination light or condensing efficiently the light emanating from a single point.

◦Aspheric lenses can be used in a wide range from the visible to infrared of 1.5μm wavelength.
◦There are two types of AGL-31.7P with a reduced spherical aberration by the plano convex lens of BK7 and AGL-12P with high NA using (FDS-90) high refractive index glass (FDS90).
◦An aspheric shape can be produced by using a special polishing equipment. Polished Aspheric lenses do not have shrinkage, cracking and chipping which usually appear in molded aspheric lenses.
