Achromatic lens

Achromatic lens assemblies offer several advantages:

  1. Enhanced image quality: Achromatic lenses enhance image brightness and clarity by eliminating color fringes, especially beneficial for polychromatic imaging.
  2. Optimal light transmission efficiency: Unlike singlet lenses, achromatic lenses maintain consistent on-axis performance even with larger aperture sizes, enabling the utilization of the entire clear aperture.
  3. Cost-effective manufacturing: While more advanced alternatives exist, achromatic lenses offer significant correction at a more reasonable cost, making them the most economical option for obtaining clear white light images for most applications.

The lens’s design will be tailored to suit the correction needed for the particular application. Occasionally, we may integrate aspheric characteristics to mitigate both spherical and chromatic aberrations.
