advantages of aspherical glass lenses

  • Aspherical lenses can focus light on a single point whereas spherical lenses cannot focus light properly.
  • Spherical lenses have low coupling efficiency and narrow optical axis - aspherical lenses have greater tolerance and are easy to adjust with LD chips.
