Aspheres are optical lenses that feature a non-spherical but rotationally symmetric radius of curvature. Unlike spherical lenses, they have a radius of curvature that varies from the center of the lens to the edge which reduces the point of light reception. This has a positive impact on common optical aberrations allowing for an improved single element solution for applications like collimating the output of a fiber or laser diode, coupling light into a fiber, spatial filtering, or imaging light onto a detector. Our Infrared aspheric lenses are often used for collimating light from mid-wavelength infrared (MWIR) and long-wavelength infrared (LWIR) laser sources, including Quantum Cascade Lasers (QCLs). We also offer acylindrical lenses, which provide the advantages of aspheres in one-dimensional focusing applications and thermal imaging lenses that focus infrared light without introducing spherical aberration.
Lightpath offers both standard, and custom optical coatings for its infrared prisms. Those include Anti Reflective (AR), High Durability AR, Spectral Filters, and protective Diamond Like Carbon (DLC) coatings.
