Custom Lenses

Excelitas precision spherical lenses can be customized in lens size and radius curvature to serve your specific application best. Our infrared spherical lenses are specially designed to meet the needs of demanding military applications throughout the infrared. Using our advanced plasma source (APS) coating technology, these spherical lenses offer superior resistance to environmentally-induced damage degradation and enable precise control over part distortion on high aspect ratio parts.

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 offers 3 µm to 14 µm thermal infrared imaging lenses, which can be customized from a variety of substrate materials, including CaF2, ZnS, ZnSe, Ge, Si, and GaAs lenses from 6 mm to 250 mm diameters with a typical surface flatness of λ/10 (at 633 nm). In addition, our advanced plasma source (APS) coating technology for highly densified thin films provides superior environmental durability.

Excelitas high-precision infrared CO2 laser lenses are customized from a variety of substrate materials, including Ge, ZnSe, ZnS, and Cleartran. Using our substrate fabrication and coating leading-edge process technologies, our CO2 laser lenses minimize subsurface damage for excellent Laser Damage Thresholds.

Excelitas multispectral lenses have high reflectivity or transmission at multiple wavelength bands (808 nm, 1064 nm, 1570 nm, 3 µm - 5 µm) with excellent wavefront quality. These features enable common aperture FLIR applications while maintaining a high laser damage threshold.
