  • Reduce Spherical Aberration
  • Multiple coating options available
  • various numerical apertures available

Precision aspherical Lens can eliminate spherical aberration and improve the accuracy of focusing and collimating for various laser applications. A precision aspherical Lens with a low numerical aperture is designed to preserve the shape of the beam, while a high precision aspherical Lens with a high numerical aperture collects all available light sources to maintain beam power over long distances. Applications include targeting systems, barcode scanners, laser diode to fiber coupling, optical data storage, or biomedical lasers.
