Holmarc’s cylindrical achromatic lenses are used to focus polychromatic light in one dimension with reduced spherical and chromatic aberrations. Holmarc’s cylindrical achromatic lenses are available either as uncoated or coated (single layer MgF2 or broadband AR). When used with monochromatic light source, these lenses produce smaller spot size than standard cylindrical lenses.
