Newport’s Aspherical achromatic lenses consists two cemented elements to provide optimal color correction and provide smallest RMS spot size close to the diffraction limit. These lenses can be used within the wavelength regime of 400-2000nm. However, the color and spherical aberration correction is only optimized over the wavelength regime of 400-700nm. The Aspherical achromatic lenses not only have superior color correction comparing to standard achromats, but also has very similar spherical aberration corrections to those of machined aspheres. To reduce the wavefront errors arising from the standard achromats the second surface of these aspherical achromats are fused with a molded polymer surface. It is an ideal choice for Imaging, Microscopy, Fiber coupling, Scanning, and other applications that use a broadband laser or normal light sources.
