Excelitas high-performance visible and infrared aspheric lenses offer a unique combination of high surface accuracy to achieve small, focused spot sizes and low surface roughness for minimal scatter and loss. These aspheric lenses feature sophisticated, multi-layer thin film coatings that deliver multispectral performance and a high laser damage threshold. Our aspheric lenses are produced with a densified structure to yield exceptional environmental stability making them ideal for demanding applications that require broadband or multispectral operation from the visible through the infrared, such as military range finding and target designation.
Excelitas UV and Visible aspheric lenses are produced using MRF technology. Our infrared aspheric lenses are manufactured utilizing single-point diamond turning technology, enabling highly accurate reproduction of virtually any rotationally symmetric aspheric shape. Diamond turning can also be used to create a surface diffractive phase profile allowing for more sophisticated functionality, such as the achromatization of single-element lenses.
