Visible Antireflection Coated Achromatic Aspherical Lenses

Aspherical achromatic lenses consist of two cemented elements which provide superior color correction and the smallest RMS spot size closest to the diffraction limit. The second element of the achromatic lens is aspherical to reduce wavefront errors arising from standard spherical achromats.

425-675 nm visible antireflection coating
Superior color correction performance than standard achromats
Minimize spherical aberration for monochromatic sources
Ideal for coupling from broadband multimode fibers or extended sources
Similar spherical aberration correction to machined aspheres
Superior performance to singlet lenses

Achromatic Asphere Design

Aspherical achromatic lenses consist of two cemented elements, a positive low-index crown glass lens element cemented to a negative high-index flint glass lens element. These elements are carefully selected to cancel chromatic aberration at two well separated wavelengths; which provide superior color correction and the smallest RMS spot size closest to the diffraction limit. The second element of the achromatic lens is aspherical to reduce wavefront errors arising from standard spherical achromats. These aspherical achromatic lenses are the ideal choice for imaging, fiber coupling, scanning, and other applications that use a broadband laser or white light sources.

Broadband Visible AR Coatings

Achromatic aspheres utilize a broadband visible coating on the front side to provide optimal transmission. The antireflection coating is applied to the front surface, whereas the back surface has a molded aspheric polymer cap with a protective seal.

Design Wavelengths

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 compared to standard achromats, but also have very similar spherical aberration corrections to those of machined aspheres.
