Product Description

Dia17mm 400-925nm AR Coated Optical Achromatic Doublet Lens
 
CPG glass lenses are made from either the highest grade of BK7 optical glass or fused silica. The fused silica lenses are ultra-violet quality synthetic fused silica. They are best for applications that require either the superior UV or IR transmission, or the improved hardness of silica. We have a vast range of different diameters from 2.5mm to 1000mm and focal lengths from 8.0mm to 5000mm.

 Diverge incident light
Reduce spherical aberration


Descriptions:

Spherical aberration occurs because spherical surfaces are not the ideal shape with which to make a lens, but they are by far the simplest shape to which glass can be ground and polished and so are often used. Spherical aberration causes beams parallel to, but distant from, the lens axis to be focused in a slightly different place than beams close to the axis. This manifests itself as a blurring of the image. Lenses in which closer-to-ideal, non-spherical surfaces are used are called aspheric lenses. These were formerly complex to make and often extremely expensive, but advances in technology have greatly reduced the manufacturing cost for such lenses. Spherical aberration can be minimized by careful choice of the curvature of the surfaces for a particular application: for instance, a Plano-convex lens which is used to focus a collimated beam produces a sharper focal spot when used with the convex side towards the beam source.
