Aspheric Condenser Lens 20mm Diameter 12mm Focal Length

AGL-20-12P

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.

Details

◦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.

Guide	Please contact our Sales Division for Aspheric Condenser Lenses with anti-reflection coating.
Remark	-
Attention	When the parallel light is incident from the back surface (flat), spherical aberration will not condense into a large point. Since an aspheric plano convex lens is a single lens, the focal length will change depending on the wavelength. Transmissions losses due to reflection off the front and rear surfaces of the lens can be minimized by coating the surfaces. Consult our Sales Division for anti-reflection coatings suitable for your application.
